Eight feet by eight feet (8' X 8') is a square area. The answer is 64 square feet.
But eight times eight feet is 64 (linear) feet, because 8x8=64.
If you mean y = 8x+15 then it is a straight line equation whereas 8 is the slope and 15 is the y intercept
8x2 + 15x + 7 = 0 factors to(8x + 7) (x + 1) = 0Therefore the 2 linear equations are:1. 8x + 7 = 0Thus 8x = -7x = -0.875and2. x + 1 = 0Thus x = -1
y=mx+c0=2x+5y=8x+2x=23
You can't simplify that. And you can only calculate a numeric value if you know what values the variables have.
Choose any value for x. Calculate 8x to get the corresponding value for y.
288 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
Y=8x-3

Area_triangle = base x height x 1/2 ⇒ 36 = (8x) x 4 x 1/2 ⇒ 8x = 18 ⇒ x = 21/4 (= 2.25)
i dont know 8x+5y=89
