Find the value of c that makes t – 22t+c a perfect square trinomial.
Verizon [17]

Answer:

c = 121

Step-by-step explanation:

Given

t² - 22t

To complete the square

add ( half the coefficient of the t- term )² to t² - 22t

= t² + 2(- 11)t + (- 11)²

= t² - 22t + 121

with c = 121

Thus

t² - 22t + 121 = (t - 11)²

If l || m,find the value of x, (8x + 20) (11x-31)
allochka39001 [22]

Answer:

x=17

Step-by-step explanation:

8x+20=11x-31

We simplify the equation to the form, which is simple to understand  

8x+20=11x-31

We move all terms containing x to the left and all other terms to the right.  

+8x-11x=-31-20

We simplify left and right side of the equation.  

-3x=-51

We divide both sides of the equation by -3 to get x.  

x=17
