Divide both side by 2 ad you get x=80
Answer:
0.8
Step-by-step explanation:
9(0.5y+0.4)=590.1y+1.3)+0.3
4.5y+3.6=0.5y+6.5+0.3
4.5y+3.6=0.5y+6.8
4.5y-0.5y=6.8-3.6
4y=3.2
y=0.8
Answer:
Expression for area = 3x² - 15x - 42
Step-by-step explanation:
Given that:
Length of rectangle desktop = 3(x+2) = 3x+6 units
Width of rectangle desktop = x - 7
Area of rectangle desktop = Length * Width
Area of desktop = (3x+6)(x-7)
Area = 3x(x-7) +6(x-7)
Area = 3x² - 21x + 6x - 42
Area = 3x² - 15x - 42
Hence,
Expression for area = 3x² - 15x - 42
