Answer:
Step-by-step explanation:
A = 
h = 10 cm , b = 17 cm
A = 10 × 17 ÷ 2 = 85 cm²
Assume that 7 is a. We already know that c = 25. The equation is c^2 - a^2 = b^2.
25^2= 625 7^2= 49 625-49= 576
Square root of 576 = 24
The length of thee other leg is 24.
An x intercept occurs whenever y=0.
y=(x-4)(x+2)
So for y=0, x=-2 or 4, so the x-intercepts are:
(-2, 0) and (4, 0)
Only (-2, 0) is within your answer choices.
