Answer:
946
Step-by-step explanation:
Let's make an equation :
34% of x = 321.8
Covert 34% into decimal by dividing by 100 :
34 ÷ 100 = 0.34
Rewrite equation with decimal form :
0.34x = 321.8
Divide both sides by x to make x the subject :
x = 321.8 ÷0.34
x = 946.470588235
To the nearest whole number will be 946 as 4 rounds it down
So our final answer will be 946
Hope this helped and have a good day

Answer:
1. The zeros are at x = 0 and x = –10
2. The zeros are at x = 3 and x = 4
Step-by-step explanation:
1. f(x) = x (x + 10)
Multiplying any number by 0 = 0,
so f(x) = 0 when...
• x = 0
or
• x + 10 = 0 (if you subtract 10 from both sides, you get x = –10)
2. f(x) = x (x - 3) – 4 (x - 3)
Use distributive property to expand
x² – 3x – 4x + 12
Combine like terms
x² – 7x + 12
Factor
(x – 3) (x – 4)
(You could have also just noticed in the original function that both x and –4 were multiplied by (x – 3) and factored then.)
So f(x) = 0 when...
• x – 3 = 0 (add 3 to both sides to get x = 3)
or
• x – 4 = 0 (add 4 to both sides to get x = 4)

Drag an answer to each box to complete this paragraph proof. Given: Triangle ABC Prove: m/A= 66 A B (5x) By the C (x + 10) m/A+m/B +m/C= 180°. Using the the sum of the angles in a triangle is equal to 180°. Therefore, solve for x, first combine like terms to get 6x + 100 = 180. Using the (5x) +90° + (x + 10) = 180°. To 6x = 80. Then, using the division property of equality, x = 13. To find the measure of angle A, use the substitution property to get m/A = 5(13). Finally, simplifying the expression gets mA = 663"
The value of A has been illustrated, computed and proven based in the triangle given.
How to calculate the triangle?It should be noted that that a triangle is a shape that has three sides and the value of the addition of all the angles are equal to 180°.
Based on the information that's given, it should be noted that the value of angle A, angle B, and angle C will be equal to 180°.
In this case, the following can be deduced:
A = 5x
B = 90°
C = x + 10°
Therefore, A + B + C = 180° (sum of angles in a triangle)
5x + 90 + x + 10 = 180°
6x = 180° - 90° - 10°
6x = 80°
x = 80/6
x = 13 1/3
Therefore, the value of A will be:
= 5x
= 5 × 13 1/3
= 66 2/3
Therefore, A is 66 2/3.
