Answer:
Step-by-step explanation:
Surface area formula= 6×side^2.
1. Side=4=>area=6×4^2=6*16=96 inches^2.
2.side=8=>area=6×8^2=6*64= 384 inches^2
3. 384+96=480 inches^2
Answer:No it can't.
Step-by-step explanation:
First, isolate x in x-4y=11 because 1 is x's coefficient.
x-4y=11
x=11+4y
Now, substitute 4y+11 for x in 5x-7y=-10.
5x-7y=-10
5(4y+11)-7y=-10
20y+55-7y=-10
Add all coefficients.
13y+55=-10
Isolate y by subtracting 55 from both sides.
13y+55=-10
13y=-10-55
13y=-65
y=-5
Now substitute -5 for y in your first equation.
x=11+4y
x=11+4(-5)
x=11-20
x=-9
Your answer would be (-9,-5).

13+5=18
The large bag would be 18 because you have to add 5 more ounces than 13
The ratio 1:2 means there are twice as many dimes as there are quarters. An expression could be n=2d, n being number of quarters, d being number of dimes.
