Answer:
x^2 + 7x + 3 in^2.
Step-by-step explanation:
The area of the whole frame = (5x + 3)(x + 6)
= 5x^2 + 33x + 18
So the area of the rim = 5x^2 + 33x + 18 - (4x^2 + 26x + 15)
= x^2 + 7x + 3 in^2.
If he is selling shovels at $19 each, the answer of $153 would be incorrect. If you take $153 and divide that by 8 (shovels) you will get each shovel being a price of $19.125 each.
The overall answer of $153 could be reasonable but the overall price from selling 8 shovels will actually be $154 not $153.
Answer:
She drove 4 minutes
Step-by-step explanation:
Answer:
4x-2y =42 is the required equation
Step-by-step explanation:
given equation is,
4x-2y -7=0---------eqn1
parallel equation of given equation is
4x -2y+k =0-------eqn 2
now passing it through (9,-3), we get,
4×9 + 2×3 +k = 0
or,36+6+k =0
or,42+k =0
or, k= -42
putting the value of k in eqn2
4x-2y - 42=0
4x-2y = 42
The surface are of a rectangular prism is:
A=2(xy+xz+yz), where x,y, and z are the dimensions of the prism, in this case:
A=2(4*6+4*8+6*8)
A=2(24+32+48)
A=2(104)
A=208 cm^2
