Answer:
x=2
Step-by-step explanation:
3(3x+10)=50−x
The first step is to distribute the 3
3*3x + 3*10 = 50-x
9x+30 = 50-x
Add x to each side
9x+x+30 = 50-x+x
10x+30 = 50
Subtract 30 from each side
10x+30-30 = 50-30
10x= 20
Divide each side by 10
10x/10=20/10
x =2
3x^2 + 8x - 4 - (6x^2 - 5x + 3)....distribute thru the parenthesis
3x^2 + 8x - 4 - 6x^2 + 5x - 3 .....combine like terms
-3x^2 + 13x - 7 <==
The answer will be C.) 70 square feet
253 * 0.27= 68.31 (discounted price)
253-68.31 OR 253*0.73= 184.69 (sale price)
Factor: 4x^2+12x+9
=2x+3 so it’s A
