Answer:
Algebraic Expression: 5<em>n</em>
a. 5(15) = 75$
b. 5(25) = 125$
c. 5(35) = 175$
d. 5(45) = 225$
Step-by-step explanation:
If <em>n</em> represents the amount of pools Mark has cleaned, and he earns $5 for each pool, then 5n will be the algebraic expression. As <em>n</em> represents the number of pools he has cleaned, we need to <u>plug in</u> the given numbers to get the answer, hence [5(15), 5(25), 5(35), 5(45)]. Multiply $5 by the given numbers to get the amount of money Mark would earn if he cleaned the amount of pools.
Answer:
Right angled and isosceles
Answer:
2x^2 +2x-4
——————
2x^2-4x+2
Factor out 2 from the expression
2(x^2+x-2)
—————-
2(x^2-2x+1)
Write x as a difference
2(x^2x-x-2)
—————-
2(x^2-2x+1)
Use a^2-2ab+b^2=(ab)^2
2(x^2x-x-2)
—————-
2(x-1)^2
Reduce the fraction with 2
x^2x-x-2
—————-
(x-1)^2
Factor out x from the expression
X*(x^2)-x-2
—————-
(x-1)^2
Factor out negative sign from the expression
X*(x+2)-(x-2)
—————-
(x-1)^2
Factor out x+2 from the expression
(x+2)(x-1)
—————-
(x-1)^2
Simplify the expression
x+2

Answer:
X=15
Step-by-step explanation:
Yes, you are right.
The given equation is
X+U=25
If U=10, then we substitute to obtain:
X+10=25
Subtract 10 from both sides to get:
X=25-10
Simplify to get:
X=15
