The answer is -4 because -4^7=-16384
Answer:
$147
Step-by-step explanation:
Bridget gets: x
Stephen gets: 3x
Richard gets: 2(3x) = 6x
Total = 10x = 490
x = 49
Stephen gets: 3x = 3(49) = $147
C if im correct A 180 ft board is cut into 3 pieces........ so 60,120,180!
Answer: 1kg: 4kg
Calculation/Explanation:
Divide both sides of the ratio by "2" It now is 1kg:4kg
V=x^3+5x^2-57x-189
Width: W=(x+3) in = 15 in →x+3=15
Solving for x:
x+3-3=15-3→x=12
With x=12 the Volume would be:
V=(12)^3+5(12)^2-57(12)-189
V=1,728+5(144)-684-189
V=1,728+720-684-189
V=1,575
V=W*D*H
Depth: D
Height: H
with H>D
V=1,575; W=15
Replacing in the equation above:
1,575=15*D*H
Dividing both sides by 15
1,575/15=(12*D*H)/15
105=D*H
3*5*7=D*H
D<H
If D=5→H=3*7→H=21
If D=7→H=3*5→H=15
