All you have to do, is combine like terms. Let's go through it:

(4x^2-8x+7)+(3x^2-2x-5)

Arrange it so you can easily combine like terms:

4x^2+3x^2-8x-2x+7-5 = 7x^2-10x+2

So, your answer for the sum is 1) 7x² - 10x + 2

How do you find the volume, in cubic inches of a prism?
Margaret [11]

Answer: V= Area of the base x the height

Simplify the following expression.( Fraction form)<br><br> 7-5/6 * 7-7/6
Ipatiy [6.2K]

Answer:

1295/36

Step-by-step explanation:

the statement tell us:

(7-(5/6))*(7-(7/6))

we have:

(7-(5/6))=((6*7)-5)/6=(42-5)/6=37/6

and we have:

(7-(7/6))=((6*7)-7)/6=(42-7)/6=35/6

we need multiply both terms:

(37/6)*(35/6)=(37*35)/(6*6)

finally we have

1295/36

ch4aika [34]
3,6,12...

this is a geometric sequence with a common ratio of 2. That means u multiply each term by 2 to find the next term.

start with 3
3 * 2 = 6
6 * 2 = 12
12 * 2 = 24...this would be ur next term

so ur answer is : multiply by 2
