2x^3 + 3x^2 + x + 1
=2x^3 + 3x^2 + 3x^2 - 3x^2 + x + 1
=2x^3 + 6x^2 - 3x^2 + x + 1
=2(x^3 + 3x^2) - 3x^2 + x + 1
=2x^2*(x+3) - 3x^2 -9x + 9x + x +1
=2x^2*(x+3) - 3x(x+3) + 10x +1
=2x^2*(x+3) - 3x(x+3) + 10x + 30 - 30 +1
=2x^2*(x+3) - 3x(x+3) +10(x+3) -29
The first three terms can be divided by (x+3) evenly so the remainder is -29
9+x- -7= -19
would be the answer
Answer=56 ounces
First lets find a conversion equation for pounds to ounces...
1pound=16ounces
9pounds=9*16=144ounces
3pounds=3*16=48ounces
Given the data, the following equation can be made, where x is equal to the weight of her science textbook.
144=48+40+x
144=88+x
subtract 88 from both sides
56ounces=x
The science textbook weighs 56ounces
Answer:
The equation is y = 6x - 5
Step-by-step explanation:
The equation is y = mx + b
7 = 2m + b
-5 = b (since x = 0)
Plug back in the first.
7 = 2m - 5
2m = 12
m = 6
