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
You can't simplify that. And you can only calculate a numeric value if you know what values the variables have.
y=mx+c0=2x+5y=8x+2x=23
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
