Answer:
3rd option
Step-by-step explanation:
y = x² + 2x - 35
consider the factors of the constant term (- 35) which sum to give the coefficient of the x- term (+ 2)
the factors are + 7 and - 5 , since
7 × - 5 = - 35 and 7 - 5 = + 2 , then
y = (x + 7)(x - 5) ← in intercept form
x = 37
Power Theorem: 10 x (10 + 26) = 8 x (8 + x)
360 = 8 x (8 + x)
8 + x = 45
105 mm^3
The volume formula for a triangular prism is (height x base x length) / 2.
(5 x 6 x 7) / 2 = 105 mm cubed = 105 mm^3
-3x - 10 =5
-3x = 15
x = -5
2x + 6 = -8
2x = -14
x = -7
