Answer:
x^3+3x^2-7x+15
Step-by-step explanation:
first you've got to distribute x through (x^2-2x+3)
x^3-2x^2+3x, then distribute the 5 through (x^2-2x+3)
5x^2-10x+15 now you add that to x^3-2x^2+3x
x^3+3x^2-7x+15
Answer:
4 2/3
Step-by-step explanation:
(m-4) (3m-2)=0
Use the zero product property to find the zeros
m-4 = 0 3m-2 =0
m =4 3m =2
m = 2/3
We want the sum of the zero's
4+ 2/3
4 2/3
Answer:
8.625 ft for each side.
Step-by-step explanation:
This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th is 9 (although i doubt saying 1th is right, but just because).
Answer:
35.5 cm
Step-by-step explanation:
The perimeter (P) is calculated as
P = (2 × 6.75 ) + (2 × 
)
= 13.5 + (2 × 11) = 13.5 + 22 = 35.5 cm
Answer:
2.0 x 10^11
Step-by-step explanation:
2.6 divide it by 1.3 and get 2.0. 9+2 = 11. Together with the, it would be 10^11. That how I got 2.0 x 10^11
Hope this Helps, have a nice day!
