If RY + YC = RC
7x+4=10x-2
3x=6
x=2
18+18=36=RC
The value of RC is 36
Answer:
2x² + 19x + 45
Step-by-step explanation:
(x + 5)(x + 1) + (x + 5)(x + 8) ← expand both sets of factors using FOIL
= x² + 6x + 5 + x² + 13x + 40 ← collect like terms
= 2x² + 19x + 45
For every function you need evaluate the function for every value in the domain D. And the collection of this values correspond to the range of the function.

12 x 8 = 96
96/2 = 48
it's an area equation so 48 m^2
