Write an expression that is equivalent to 9c - 12 - 15c-8-36 • Which sum is equivalent to 90 – 12 – 15c – 8 – 3c?
-9€ +(-12)+(-15c) + (-8) +(-30)
9c+(-12)+(-15c) +(-8) +(-30)
9c+(-12) - 15c +(-8) – 30
9c + 12 + 15c+8+ 30

just put them in order

step-by-step explanation:

it could be a ..idk tho

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
