Answer:
The length and width are
r-11 and r+5
Step-by-step explanation:
The given trinomial is

To factor, we need to split the middle term to get:

We now factor by grouping to obtain;

We collect common factors again to get:

Therefore the length and width are
r-11 and r+5
X= 56, y= 124 z=56 because they are vertical angles
15t + <35> j (price * count sold)
Cost = <4.5>t + 5 j + 150
Profilt = Revenue - Cost = (15t + <35>j) - (<4.5>t + 5j + 150)
= 15t + <35>j - <4.5>t < - >5j - 150
= 50t - -9.5j - 150
