Answer:
6
Step-by-step explanation:
The main idea of how to solve it is to isolate the variable. Whatever you multiply, divide, add, or subtract on one side, you must do the same to the other side so that both sides are equal.
3(x-1) = 21
3(x-1) / 3 = 21 / 3
x - 1 = 7
+ 1 + 1
x = 6
Answer:
<h2>x = 3</h2>
Step-by-step explanation:
Answer:
x=-55.5
Step-by-step explanation:
Answer:
The answer is
<h2>(2x + 3)(x + 1)</h2>
Step-by-step explanation:
<u>Write 5x as a sum</u>
2x² + 2x + 3x + 3
Factorize x out
That's
2x ( x + 1) + 3( x + 1)
The final answer is
(2x + 3)(x + 1)

Answer:
The other sides of the square are
8x+12+16+8x,(8x+8x)+(12+16) and 16x+28
Step-by-step explanation:
Square:
- The all sides of a square equal.
- The sum of four angles is 360°.
- The diagonals bisect each other.
- The length of diagonals are equal.
Distributive property:
a(b+c)= ab+ac
Commutative property:
a+b= b+a
Like terms:
Like terms are terms that have the same variables and the power of the variable also same.
Given the length of the side is
=4(2x+3)+16+8x
=4.2x+4.3+16+8x [ Apply distributive property]
=8x+12+16+8x
=(8x+8x)+(12+16) [ separating like terms]
=16x+28 [Adding like terms]
The other sides of the square are
8x+12+16+8x,(8x+8x)+(12+16) and 16x+28
