lubasha [3.4K]

Answer:

x = (8+y)/3

Step-by-step explanation:

3x-y=8

Add y to each side

3x-y+y=8+y

3x = 8+y

Divide each side by 3

3x/3 = (8+y)/3

x = (8+y)/3

The length of each side of a square is 3 in. more than the length of each side of a smaller square. The sum of the areas of the
Taya2010 [7]

Answer:

L_1 = 4

And L_2 = 3 +4 = 7

Step-by-step explanation:

For this case we assume that for the first square we have the following dimensions:

A_1 = L^2_1

And we know that:

L_2 = 3 + L_1

And the area for the second square would be:

A_2 = L^2_2 = (3+L_1)^2 = 9 + 6L_1 + L^2_1

And we know that the sum of areas is 65 so then we have this:

A_1 + A_2 = 65

And replacing we got:

L^2_1 + 9 + 6L_1 + L^2_1 = 65

2L^2_1 +6L_1 - 56=0

We can divide the last expression by 2 and we got:

L^2_1 + 3L_1 -28=0

And we can factorize the last expression like this:

(L_1 + 7) (L_1 -4) =0

And we have two solutions for L_1 and we got:

L_1 = 4, L_1 = -7

Since the length can't be negative we have this:

L_1 = 4

And L_2 = 3 +4 = 7

mihalych1998 [28]

Answer:

r^2 + 14r + 33

Step-by-step explanation:

Apply the "FOIL" method for multiplying two binomials:

(r+3) (r+11) = r^2 (first terms) +

                    + 33 (last terms) +

                     + 11r (outer terms) +

                      + 3r (inner terms)

Combining ilke terms, we get:

r^2 + 14r + 33
