i got this on usatestprep.
a)2x + 5
b)2x − 5
c)x2 − 2
d)x2 + 2
The common binomial factor between the two groups after their GFCs factored out 2x + 5.
The correct option is (A)
The greatest commonfactor (GCF) of a set of numbers is the largest factor that all the numbers share.
Given: 2x³ - 5x² + 4x - 10, splits into (2x³ + 4x) + (-5x² - 10)
So, to find the GCF factorise each term
= (2x³ + 4x) + (-5x² - 10)
= 2*x*x*x+2*2*x-5*x*x-2*5
= 2x(x²+2)-5(x²+2)
= (2x-5) (x²+2)
Hence, the common binomial factor between the two groups (2x-5).

A.) Substitute the values into the vertical motion formula h=-16t^2+vt+c. Let h=0
B.) Use the quadratic formula find out how long the rocket will take to hit the ground after it is launched. Round to the nearest tenth of a second.
1.)0= -16t^2 + 135t + 76; 0.5 s
2.)0= -16t^2 + 135t + 76; 9 s
Answer:
The answer is 2.)
Step-by-step explanation:
Given initial velocity=135 ft/s
& cliff=76 foot
Given quadratic equation
⇒ (let h=0 it is given)
⇒
⇒
⇒ t=8.96≈9 s (the other root is negative)
Hence, rocket will take 9 s to hit the ground after launched.
