Answer:
(5r - 20)
Step-by-step explanation:
(3r + 14) + (Ar + B) = (8r - 6)
B = -6 - 14 = -20
A = 8 - 3 = 5
Answer:
C
Step-by-step explanation:
To find the volume of a cube, raise the value of one side to the third power. 2.5 centimeters to the third power is 15.625, which can also be expressed as the fraction 125/8
Answer:
156.25cm^2
Step-by-step explanation:
Perimeter of rectangle: 2(length + width)
P=2(x+y)......equation (1)
A= xy ...........equation (2)
From equation (1)
50=2(x+y)
Divide both by two
25=x+y
x=y-25
Then the area:
From equation (2)
A=(y-25)y
The zeros will be y-25=0 and y=0 therefore y=25 and y=0
Then their average is: (25+0)/2 = 12.5
The width is 12.5 and the length is 25-12.5 which is 12.5
X=Length=12.5
Y=width=12.5
The largest area is:
12.5×12.5
156.25cm^2
6 right ? because if it’s three hours after 2 then that would mean it’s 5 and one more hour after that meaning it’s 6.
unless your asking what’s one hour after 2 meaning it would be 3.
