Answer:
quotient x² - 2x + 5
remainder (-12x+5)
Step-by-step explanation:
<u> x² -2x +5</u>
x² + 2x - 1 | x^4 + 0*x³ + 0*x² + 0x + 0
<u> |-(x^4 + 2x³ - x²)</u>
- 2x³ +x² + 0x
<u> -(-2x³ - 4x² + 2x)</u>
5x² - 2x + 0
<u> -( 5x² +10x -5)</u>
-12x + 5
x² - 2x + 5 + (-12x + 5)/(x² + 2x - 1)
Answer:
so i would say B because it would make good sense with the $
Step-by-step explanation:
This a linear equation because each test score is a constant 4 greater than the previous score. So the slope of the line is 4.
y=4x+b and using any point we can find b, I'll use (3,65)
65=4(3)+b
65=12+b
b=53 so
y=4x+53 so on her 9th test...
y(9)=4(9)+53
y(9)=89
Surface are just means that you need to find the area of every face, then add.
TO find the Area of the rectangle do 16*8 = 128
For the triangle the area formula is b*h*1/2 So do 7*8*1/2= 28
There are four sides total and two triangles and two rectangles so 28+28+128+128= 312
SO the surface area is 312 in cubed
