Answer:
The remainder after dividing x4 + 3x3 − 8x2 + 5x − 9 by x + 5 is 16
Step-by-step explanation:
We have to divide x4 + 3x3 − 8x2 + 5x − 9 by x+5
First of all we solve the first term of the dividend.
We have the divisor x+5
If we multiply it by x^3 than we get the first term of our dividend.
x^3(x+5) = x^4+5x^3
x4 + 3x3 − 8x2 + 5x − 9
x^4+5x^3
- -
___________________
-2x^3-8x^2+5x-9
Now we have the first term of dividend as -2x^3
Now we will multiply x+5 by -2x^2 to get the first term
-2x^2(x+5) = -2x^3-10x^2
-2x^3-8x^2+5x-9
-2x^3-10x^2
+ +
______________
2x^2+5x-9
Now the first term of the dividend is 2x^2
So we will multiply x+5 by 2x
2x(x+5)= 2x^2+10x
2x^2+5x-9
2x^2+10x
- -
_________
-5x -9
Now the dividend we have is -5x-9
We will multiply x+5 by -5
-5(x+5) = -5x-25
-5x -9
-5x-25
+ +
______
16
Thus the remainder after dividing x4 + 3x3 − 8x2 + 5x − 9 by x + 5 is 16....
Answer:
Can you put a picture? No picture is showing up for me
Step-by-step explanation:
Step-by-step explanation:
a2+b2=c2 is phythagorean
A....if its wrong im sorry but i believe its a because you will do 4x4 and will get the sum of 16ft square
Step 1: Find the area of the bases (triangles)
A = 1/2 * base * height
A = 1/2 * 16 * 6
A = 48
48 + 48 = 96
Area of the triangles = 96 cm^2
Step 2: Find the area of the sides (rectangles)
A = base * height
A1 = 16 * 12
A1 = 192
A2 = 10 * 12
A2 = 120
120 + 120 = 240
240 + 192 = 432 cm^2
Step 2: Add the areas together
96 + 432
528 cm^2
Hope this helps!! :)
