(a). 8x + y = 20, where (b). y = x2 - 2x + 4
So where y is in equation (a), substitute in the value of y in (b).
8x + (x2 - 2x + 4) = 20
8x + (4) = 20
Get rid of the 4 on both sides (since what you do to one side, you must do to the other)
8x + 4 - 4 = 20 - 4
8x = 16
Get rid of the 8 to leave x on its own
8x ÷ 8 = 16 ÷ 8
x = 2
So now that you have x, find y but substituting in the value you just found (2) into one of the starting equations.
8x + y = 20 where x is 2.
8(2) + y = 20
16 + y = 20
Minus 16 from both sides
y = 20 - 16 = 4
So x is 2 and y is 4

option-A
Step-by-step explanation:
we are given
divisor is
Dividend is
=x-2
so, we can use synthetic division
so, we can write our expression as
so,
option-A
You're basically doing 890 divided by 1, so the answer would be 800.. 800 ones.
Answer:
V = 792 m3
I am kinda guessing on this since you didn't provide a unit or label what the height, width, and length are. Also you should specify what prism...
