Answer: calculator boi
Step-by-step explanation:
The volume of a cube is length x width x depth. In a cube all would be equal therefore.
<span>x^3= 64 </span>
<span>x =4 </span>
<span>The area in square feet of one side would then be length x width </span>
<span>There are 6 sides so the surface area of the cube would be </span>
<span>(4)(4)(6) = 96 square feet</span>
Answer:
(-4, -1)
Step-by-step explanation:
-3x - 8y = 20; y = 5x + 19
y = 5x + 19; -3x - 8y = 20
y = 5x + 19
-3x - 8y = 20
-3x - 8(5x + 19) = 20
-43x - 152 = 20
-43x - 152 + 152 = 20 + 152
-43x = 172
-43x / -43 = 172 / -43
x = -4
y = 5x + 19
y = (5)(-4) + 19
y = -1
Answer:
She subtracted the coefficients instead of dividing them
Step-by-step explanation:
5/68
5 can go into 68 13 times with a remainder of 3
So we add a decimal point and a zero.
Carry the 3 and zero down making 30
5 can go into 30 6 times making the answer 13.6
