Answer:
Total surface area of cube = 294 cm²
Step-by-step explanation:
Given:
Perimeter of cube = 84 cm
Find:
Total surface area of cube
Computation:
Perimeter of cube = 12 x side
84 = 12 x side
Side = 7 cm
Total surface area of cube = 6(a)²
Total surface area of cube = 6(7)²
Total surface area of cube = 294 cm²
Answer:
9000000+20000+20+9
Step-by-step explanation:
Answer:
Any equation of the line with slope 2/3.
Parallel lines have identical slope.
Step-by-step explanation:
3y - 2x = - 24
3y = 2x - 24
y = 2/3x - 8
The slope of the line is
(9-5) / (4- -2) = 4/6 = 2/3 .
If the x-intercept is -2 and the y-intercept is 1, then the equation of the line is
y = 1/2 x + 1 .
None of the choices is correct.
Answer:
Infinite solutions
Step-by-step explanation:
5(-3x-2)-(x-3)=-4(4x+5)+13
-15x-10-x+3=-16x-20+13
-16x-7=-16x-7
-16x=-16x
-x=-x
x=x
There are infinite many solutions
