what will be the nature of roots of quadratic equation 2x²+4x-7=0?
Let us consider a quadratic equation αx² + βx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.
If Discriminant, D > 0, then roots of the equation are real and unequal.If Discriminant, D = 0, then roots of the equation are real and equal.If Discriminant, D < 0, then roots of the equation are unreal or complex or imaginary.Where,
[tex]\quad\red{ \underline { \boxed{ \sf{Discriminant, D = β² - 4αc}}}} [/tex]
Given Equation:-[tex]\red{\leadsto}\: \sf{2x^2 + 4x -7= 0} [/tex]
α = 2β = 4c = -7Now,
[tex]\quad\green{ \underline { \boxed{ \sf{Discriminant, D = β² - 4αc}}}} [/tex]
[tex]\begin{gathered}\begin{gathered}\implies\quad \sf D = 4^2-4\times 2\times ( - 7) \end{gathered} \end{gathered} [/tex]
[tex]\begin{gathered}\begin{gathered}\implies\quad \sf D = 16-( - 56)\end{gathered} \end{gathered} [/tex]
[tex]\begin{gathered}\implies\quad \sf D = 16 + 56\end{gathered}[/tex]
[tex]\begin{gathered}\begin{gathered}\implies\quad \sf D = 72 \end{gathered} \end{gathered} [/tex]
Since, Discriminant, D > 0, then roots of the equation are real and distinct.

The equation 8m+3=75 models how many months, m, it takes a tree to reach a height of 75 inches after being potted. If the tree grows the same number of inches each month, how many months does it take the tree to reach a height of 75 inches?
pls help
72 months
25 months
9 months
8 months
The equation computed simply shows that the number of months will be C. 9 months.
How to solve the equationFrom the information given, the equation 8m+3=75 models how many months, m, it takes a tree to reach a height of 75 inches after being potted.
Therefore, the number of months will be calculated thus:
8m + 3 = 75
8m = 75 - 3
8m = 72
m = 72/8
m = 9
The correct option is 9 months.

[tex]12s-4s+2=10 \\ 8s = 10 - 2 \\ 8s = 8 \\ \cancel8 s = \cancel8 \\ s = 1[/tex]
Solution:
We know that:
Given equation: 12s - 4s + 2 = 10Step-1: Combine like terms
12s - 4s + 2 = 10s(12 - 4) + 2 = 10s(8) + 2 = 10Step-2: Subtract 2 both sides
s(8) + 2 - 2 = 10 - 2s(8) = 8Step-3: Divide 3 both sides
s(8)/8 = 8/8s = 8/8 = 1Thus, the value of s is 1.

Find the area of the following shapes.
Answer:168.75 squared
Step-by-step explanation: we know that the whole of the rectangle ( including the outline) is 225 cm squared
so half of this is 225 divide by 2 and that is 112.5
but we also have a right-angled triangle that is half the half rectangle so we do 112.5 divide by 2 and that is 56.25
to finish it off we ad 56.25 with 112.5 and that is 168.75
Answer:
180mm²
Step-by-step explanation:
Area of rectangle = 15mm x 9mm
= 135mm²
EF = 15mm - 9mm = 6mm
Area of triangle = [tex]\frac{1}{2}[/tex] x 6mm x 15mm
= 45mm²
Total area = 135mm² + 45mm²
=180mm²

Mia has a loyalty card good for a 16% discount at her local grocery store. What would
her total in dollars and cents be, after the discount and before tax, if the total cost of
all the items she wants to buy is $24.50? Round to the nearest cent.
The total price in dollars and cents is twenty dollars and sixty cents.
What are discount rates?Discount rates are the reduction of actual price knowns as a benefit that a customer or a consumer enjoys in the total amount of goods or products being purchased. They are calculated by multiplying the total amount of goods bought with the discount percentage rate given.
From the given information:
Mia's loyalty card has a discount rate of = 16%The total cost of items she wants to buy = $24.50Thus, before tax deduction, the total of items bought while taking the discount rate into consideration is:
= 16% × $24.50
[tex]\mathbf{= \dfrac{16}{100} \times \$24.50}[/tex]
= $3.92
The total price after removing the discount price now will be:
= $24.50 - $3.92
= $20.58
≅ $20.60 (to the nearest cent)

m + s = 26
3m + 8s = 123
Answer:
M=17
S=9
Step-by-step explanation:
m = 17 and s = 9
Refer to the attachment for full solution . The main key here is to multiply first equation by 3 so that in both equations the coefficient of m will be same so that we can eliminate 3m and then we will solve for s and then putting value of s in any of the equation , so we can get m
Note :- You can multiply the 1st equation by 8 too for making coefficient of s same and then solving for m and then solving for s

He collected a total of 225 . If 68% of the stamps he collected were foreign, how many other stamps did he collect?
Answer:
72 stamps
Step-by-step explanation:
First, we're looking to find the number of stamps that AREN'T foreign, so we have to subtract 68% from 100%.
100% - 68% 32%Now, we know that 32% of the stamps are NOT foreign. So, next, we:

Seventy-five percent of the apple pies were sold on Tuesday, and the remainder were thrown out. If 12 apple ples were sold Tuesday, then how many were thrown out?
Answer:
4 pies
Step-by-step explanation:
Hello!
We know that 12 apple pies are 75 percent of the total apple pies.
Let x = # of pies total.
This means that 75% of x, or 0.75x is 12
Solve:
75% of x = 120.75x = 12x = 16Now, 16 is the total number of pies. To find the number thrown out, we subtract 12.
16 - 12 = 4
4 pies were thrown out
Solution:
Let "a" represent total apple pies.
Note that:
75% x a = 12 apples piesSimplify the LHS:
75a/100 = 12 apple piesUse cross multiplication:
75a = 12 x 100=> 75a = 1200Divide 75 both sides:
=> 75a/75 = 1200/75=> a = 16If there were 16 apples and 12 were sold, 4 apple pies were thrown out.
