9) x= -6
10) x= 3/2
11) x= -4,0,5
12) no solution
I've done this test before
The factor should be x+7 so, none of the above.
Hope I helped! ( Smiles )
Answer:
(- 7, - 4 )
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the turning point is
x = - 
y = x² + 14x + 45 ← is in standard form
with a = 1, b = 14 , then
x = -
= - 7
Substitute x = - 7 into the equation and evaluate for y
y = (- 7)² + 14(- 7) + 45 = 49 - 98 + 45 = - 4
coordinates of turning point = (- 7, - 4 )
The grasshopper is 5X+2-(2x-1)=3x+3 inches longer than the spider.
The answer is 41
Because 90-49
