Step-by-step explanation:

x = price of 1 bush

y = price of 1 flower

12x + 30y = 240

7x + 10y = 125

the easiest approach is now to e.g. multiply the second equation by -3 and then add both equations, and then solve the result for x.

12x + 30y = 240

-21x - 30y = -375

-----------------------------

-9x 0 = -135

-9x = -135

9x = 135

x = 15

7x + 10y = 125

7×15 + 10y = 125

105 + 10y = 125

10y = 20

y = 2

so, each bush costs $15, each flower costs $2.

The area of a rectanglular sandbox is (5x + 40) feet. Factor 5x + 40 to find possible dimensions of the sandbox
kotegsom [21]
5x+40 factors to 5(x+8). Notice how distributing the 5 back through to each term in the parenthesis gives
5 times x = 5x
5 times 8 = 40
So 5*(x+8) = 5*x+5*8 = 5x+40

Therefore, the factors are 5 and (x+8).
The dimensions of the sandbox are 5 feet by (x+8) feet.

We don't know the numeric value of (x+8) since we don't know the value of x, so we leave it as is.
