Step-by-step explanation:
In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations. For example, 3x² − 2xy + c is an algebraic expression. Since taking the square root is the same as raising to the power, is also an algebraic expression.
answer
x=14
Step-by-step explanation:
4.5(8-x)+36=102-2.5(3x+24)
36-4.5x+36=102-7.5x-60
-4.5x=42-7.5x
7.5x-4.5x=42
3x=42
x=42/3
x=14
Because GH bisects FGI, FGH=HGI
2x+1=3x-9
x=10°
so the measure of HGI is 21°
Answer:
4 units by 12 units
Step-by-step explanation:
one side of the rectangle is x, the other side is 3x.
3x(x)=48
3x²=48
x²=48/3
x²=16
√x²=√16
x=4
substitute 4 into the original dimensions
