The Diamond Rule says two factors, m and n, must multiply to get to the top number and add to get to the bottom number.
What are the possible values for m and n?
By solving a system of equations, we will see that the values of n and m are 3 and -4.
How to get the values of n and m?
We need to get two values n and m such that:
n*m = -12
n + m = -1
So this is a system of equations, to solve it, we first need to isolate one of the variables in one of the equations. I will isolate n on the second equation:
n = -1 - m
Then, replacing that on the other equation we get:
(-1 - m)*m = -12
-m - m^2 = -12
-m^2 - m + 12 = 0
This is a quadratic equation, the solutions are given by Bhaskara's formula:
[tex]m = \frac{-(-1) \pm \sqrt{(-1)^2 - 4*(-1)*12} }{2*-1} \\\\m = \frac{1 \pm 7}{-2}[/tex]
Now, let's take the first solution for m:
m = (1 + 7)/-2 = -4
Then the value of n is the other solution, (or we can use the equation for n that we found above):
n = -1 - m = --1 - (-4) = 3
Then the two numbers are 3 and -4, meaning that the correct option is the first one.

£245 increased by 25%?
Answer:
306.25
Step-by-step explanation:
What you need to do is multiply 245 by .25 (the decimal form of 25%). Then you should get 61.25, which is what the increase would be. Then, using the product, add 245 with 61.25 and you'll get the answer.
(Hope this helps)
Answer:
61.25 Euro
Step-by-step explanation:
Hopefully this is right. I'm American so I had to do a little converting with the currency. How you solve it is you multiply 245 by 25 and then divide by 100. Whenever percentage is involved think of the butterfly method.
[tex]x/250=25/100[/tex]
In this problem X is what you're trying to solve for; what the number will be AFTER the increase. The denominator will always be the original amount/price. Then on the other side you put the percentage over 100, since percentages go from 0% to 100%, kinda like quarters.

11. Write a formula for the area of the shaded region in terms of x.
2
2
x + 5
okay so basically we see two rectangles right, so we can subtract the small from the big to leave the shaded region behind: so we take the area of the big rectangle first, (x+5)*4 and then we subtract the small area which is 2*2 so that we get an equation like this: (x+5)*4 - 4 --> 4x+20-4 --> 4x+16
Solve 20% of blank = 40
Answer: 200
Step-by-step explanation:
Let the unknown number be x.
Therefore, 20%*x = 40
20% as a fraction is 1/5.
Therefore x*(1/5) = 40
Multiply both sides by 5:
x = 200

Two angles are supplementary. The measure of the larger angle is 28 more than 3 times the measure of the smaller angle.
Find the measures of both angles.
ATQ
[tex]\\ \rm\longmapsto 3x+28+x=180[/tex]
[tex]\\ \rm\longmapsto 4x+28=180[/tex]
[tex]\\ \rm\longmapsto 4x=152[/tex]
[tex]\\ \rm\longmapsto x\approx 38[/tex]
3x+28=180-38=142Let's assume that ,
x is the smaller angle
3x+28 is the larger angle
then,
ATQ,
x + 3x+28 = 180°
4x +28 = 180°
4x = 180°-28°
4x = 152°
x = 38°
putting the value of x in the larger angle
⇢3x +28 = 3 x 38° +28° = 142°
hence , the measure of the smaller angle is 38° & the larger one = 142°

Answer:
135
Step-by-step explanation:
Multiply .15 by 900
0.15 x 900 = 135
Hope this helps :)
Answer:
135
Step-by-step explanation:
To find 15% of a number, we can find 10% first then 5%
10% of 900 is 90 (900 ÷ 10 = 90)5% of 900 is 45 (half of 10% of 90)Therefore, 15% of 900 is 135We can also turn 15% into a decimal by dividing 15 by 100: 15 ÷ 100 = 0.15 Now, we can treat 'of' as × and do 0.15 × 900 which is 135.

Three pounds of apples costs $1.09. How much will 11 pounds of apples cost? Round to the nearest cent.
Answer:
Step-by-step explanation:
Comment
This is a proportion question. That means that the ratios given are equal. There are 4 facts all together. 3 are given, you have to solve for the 4th. The procedure is the same every time.
Equation (proportion)
cost of apples 1.09/ Number of apples (3) = cost of nearly a dozen (x)/Number = 11.
1.09/3 = x / 11 Cross Multiply
3x = 1.09 * 11 Combine the right
3x = 11.99 Divide by 3
3x/3 = 11.99/3
x = 3.99

Consider the complex numbers and in the complex plane below:
Find the rectangular forms of v,w,z
and enter them in that order.
Answer:
v = √2 +√2iw = -2 -2√3i . . . ("i" is not under either radical)z = 0 -3iStep-by-step explanation:
A suitable calculator can perform polar to rectangular conversion for you. If you like to do it "by hand", the conversion is ...
(r; θ) ⇔ r·cos(θ)+ r·sin(θ)i
Your numbers translate to ...
v = √2 +√2iw = -2 -2√3iz = 0 -3i_____
Additional comment
We aren't often asked to read polar graphs. The concentric rings here are taken to be 1 unit apart. The radial lines are 15° apart. Then the various points are ...
v = 2∠45°
w = 4∠-120°
z = 3∠-90°
As you can see, the TI-84 work-alike in the attachment is able to write and understand numbers in this form. Other calculators treat complex numbers as vectors [magnitude, angle], or as coordinates with a special separator (semicolon) to indicate polar coordinates vs. complex plane coordinates: (r; θ) vs. x +iy
In any event, you need to be careful to understand the units the calculator uses for angles. In the attached, we have set the angle units to degrees. Most spreadsheets default to radians.

b. It has an obtuse angle which measures less than 90°
c. It has an obtuse angle which measures greater than 90°.
d. It has an acute angle which measures greater than 90
Answer:
c
Step-by-step explanation:
an obtuse angle is an angle which is greater than 90° but less than 180° so an obtuse triangle will have an angle that measures greater than 90
Answer:
c. It has an obtuse angle which measures greater than 90°.
Step-by-step explanation:
An obtuse angle is any angle greater than 90°, and an obtuse triangle is a triangle in which one of the angles is an obtuse angle.
