T<br> ✓<br> Х<br> Find the sum of (x2 – 7x + 5) and (-3x2 - x + 10)<br> [
Zanzabum

Answer:

-2x² - 8x + 15 = 0

Step-by-step explanation:

Given the following algebraic expression;

x² – 7x + 5

-3x² - x + 10

To add the equation together;

x² – 7x + 5 + (-3x² - x + 10) = 0

x² – 7x + 5 - 3x² - x + 10 = 0

Collecting like terms, we have;

(x² - 3x²) - (7x + x) + (5 + 10) = 0

-2x² - 8x + 15 = 0

17) x-8=11

18) 9-x=5

19) x+6=7

20) x+(-4)=-18

Step-by-step explanation:

17) The difference between a number and 8 is 11

Let number = x

then the equation will be:

x-8=11

Solving:

x-8=11

x=11+8\\x=19

18) Nine less than a number is five.

Let number = x

then the equation will be:

9-x=5

Solving:

9-x=5\\-x=5-9\\-x=-4\\x=4

19) Seven is equal to a number plus 6

Let number = x

then the equation will be:

x+6=7

Solving:

x+6=7\\x=7-6\\x=1

20) The sum of a number and -4 is -18

Let number = x

then the equation will be:

x+(-4)=-18

solving:

x+(-4)=-18\\x-4=-18\\x=-18+4\\x=-14
