Answer:
5.86
Step-by-step explanation:
Use foil which is a lazy way to remember theh distributive property
goes like this
multiply
First terms
Outer terms
Inner terms
Last terms
and add them all toegethe
so
(x+2)(x+2)
First: x times x or x²
Outer: x times 2 or 2x
Inner: 2 times x or 2x
Last: 2 times 2 or 4
add them toegether
x²+2x+2x+4=
x²+4x+4
120+25x=45x
Step 1: Simplify both sides of the equation.
25x+120=45x
Step 2: Subtract 45x from both sides.
25x+120−45x=45x−45x
−20x+120=0
Step 3: Subtract 120 from both sides.
−20x+120−120=0−120
−20x=−120
Step 4: Divide both sides by -20.
−20x
−20
=
−120
−20
x=6
Answer:
x=6
