Ur answer would be 88. heres why: first u ask urself how many times does 7 go into 6? well, it can't because 6 is smaller than 7. Than look at the next digit.61 is big enough. so u do 56-61 which is 5 then u bring down ur 9. now u have 59. 7 goes into 59 8 times because 7×9 is 63 is 2 big so that leaves u with 88 reminder 3
Answer:
Below.
Step-by-step explanation:
Substitute x = 3 into each polynomial and see if the value of the polynomial is zero. If it is zero then x-3 is a factor.
Try number 1:
a(x) = x^3 - 2x^2 - 4x + 3
a(3) = 3^3 - 2(3)^2 - 4(3) + 3
= 27 - 2(9) - 12 + 3
= 27 - 18 - 12 + 3
= 9 - 18 - 9
= 27 - 27
= 0
So a(x) has (x-3) is a factor of a(x)
The other 3 polynomials are solved in the same way.
Answer:
6xy(15xy−1)
Step-by-step explanation:
40*1.2=48
1 represent the entire amount and .2 represents the tax added. When multiplied it would give you 48 as the final price.
