Answer:

Step-by-step explanation:
We have the two functions:

And we want to find:

This is equivalent to:

Therefore, we will have:

By substitution:

Simplify. Square and distribute:

Rearrange:

Combine like terms:

Z=60
because
z/-12 = -5
z= (-5)(-12)
z= 60
Answer:
Hence new dimension of new garden is 27 by 51
Step-by-step explanation:
Initial dimension of his square garden = X by X
Final dimension of his rectangular garden = L by B
Perimeter of his garden = 60 = 4X
Hence X = 60/4 = 15 ft
Area of the square garden = 15 x 15 = 225 ft²
New garden dimensions
L + 3 = 2W-----------------Eqn 1
2(L+W) = 60---------------Eqn 2 (since both shapes have the same perimeter)
solving both equations simultaneously
From equation one L = 2W-3, it's now substituted into equation 2
from equation 2, 2L+2W= 60
Hence 2(2W-3) + 2W = 60
W = 27 ft
L= 2(27)-3= 51 ft
Hence length and breadth of new garden is 27 by 51

P.S. if that is u in your pfp you are rlly pretty
Simplifying
9x + -3(x + 8) = 6x + -24
Reorder the terms:
9x + -3(8 + x) = 6x + -24
9x + (8 * -3 + x * -3) = 6x + -24
9x + (-24 + -3x) = 6x + -24
Reorder the terms:
-24 + 9x + -3x = 6x + -24
Combine like terms: 9x + -3x = 6x
-24 + 6x = 6x + -24
Reorder the terms:
-24 + 6x = -24 + 6x
Add '24' to each side of the equation.
-24 + 24 + 6x = -24 + 24 + 6x
Combine like terms: -24 + 24 = 0
0 + 6x = -24 + 24 + 6x
6x = -24 + 24 + 6x
Combine like terms: -24 + 24 = 0
6x = 0 + 6x
6x = 6x
Add '-6x' to each side of the equation.
6x + -6x = 6x + -6x
Combine like terms: 6x + -6x = 0
0 = 6x + -6x
Combine like terms: 6x + -6x = 0
0 = 0
Solving
0 = 0
