X²＋7x－30
＝x²＋10x－3x－30
＝x(x＋10)－3(x＋10)
＝(x＋10)(x－3)
Hope my answer helped u :)
7 5/21 I think that would be the one that can cover it but not have to much left.
You might need a second opinion.
Answer:
x = 
Step-by-step explanation:
given, 50 - x^2 = 0
add x^2 to both sides, 50 = x^2
square root both sides, 
= 
simplify, 50 / 5 = 10 / 5 = 2
you have a pair of 5's, and a 2, = x
Answer:
12
Step-by-step explanation:
Pythagorean Theorem states that
a² + b² = c²
plug in your terms
9² + b² = 15²
81 + b² = 225
then subtract 81 from 225 to get your b²
b² = 144
then find the square root of 144
the square root is 12 because 12 x 12 = 144

Answer: 25</h3>
Explanation:
The "large cars" pie slice takes up 7% of a full circle. This means that the degree measure of this slice takes up 7% of a full 360 revolution.
7% of 360 = 0.07*360 = 25.2 degrees
This then rounds to 25 degrees
