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
Solve the second equation for y
Substitute the given value of y into the first equation
Solve the equation for x
Substitute the given value of x into the second equation
Solve the equation for y
The possible solution of the system is the ordered pair (x,y)
X-4/2 = 10
x+-2=10
x-2=10
x-2+2=10+2
x=12
Answer:4.25, so about 4 or 5
Step-by-step explanation:
1/4 = x/17
-Cross multiply-
4*x = 1*17
4x = 17
-divide-
17/4 = x
x = 4.25
Answer:
Total Cost - 54c
Step-by-step explanation:
