Answer:
x = -7
Step-by-step explanation:
-5( x + 3 ) = 20
Distributive property ( multiply whatever is in the parenthesis by -5)
-5 * x + -5 * 3 = 20
-5x - 15 = 20
Add 15 on both sides
-5x - 15 + 15 = 20 + 15
-5x = 35
Divide by -5 on both sides to isolate the variable
-5x/-5 = 35/-5
x = -7
Check...
Substitute the "x" with -7 since we already got that as our solution
-5( x + 3 ) = 20
-5( -7 + 3 ) = 20
Distributive property
-5 * -7 + -5 * 3 = 20
35 - 15 = 20
20 = 20 CORRECT
Hope this helped!

Answer:
x = 1/2
Step-by-step explanation:
4x - 3 + 5 = 2x + 7 - 8x
4x + 2 = -6x + 7
10x + 2 = 7
10x = 5
x = 5/10
x = 1/2
Answer:

Answer: 5sqrt(35)
Step-by-step explanation:
If the ratio of the side lengths is 1:4, since the ratio of the areas is the square of the ratio of the side lengths, the ratio of the areas is 1:16.
This means the area of square ABCD is 14000/16 = 875.
Therefore, AB=sqrt(875)=5sqrt(35).
