Answer:
130 ft^2
Step-by-step explanation:
SA= surface area
SA= 2*l*w + 2*l*h + 2*w*h
l= length = 10
w= width =5
h = height = 1
SA= 2*l*w + 2*l*h + 2*w*h
SA= 2*10*5 +2*10*1+2*5*1
SA= 100+20+10
SA= 130 ft^2
Answer:
2(x+y+11)
Step-by-step explanation:
2(x+5)+3y+12−y
Use the distributive property to multiply 2 by x+5.
2x+10+3y+12−y
Add 10 and 12 to get 22.
2x+22+3y−y
Combine 3y and −y to get 2y.
2x+22+2y
Answer:
the coefficients are 4 and 5 and 1
Step-by-step explanation:
the 4 and 5 have a variable in front of them. There's a ghost 1 in front of the x, because it's value is 1 times whatever the value of x is
Answer:
4.7 cm
Step-by-step explanation:
= 7 so side length of the square is 7
7 x 4 = 28 so perimeter is 28cm
28 - 9.3 - 9.3 = 9.4
9.4 / 2 = 4.7 cm
