Let f(x) = 7x^2-5x+3 and g(x) = 2x^2+4x-6

Troyanec [42]

Answer:

$\large\boxed{A.\ f(x)+g(x)=9x^2-x-3}\\\boxed{B.\ f(x)-g(x)=5x^2-9x+9}\\\boxed{g(x)-f(x)=-5x^2+9x-9}$

Step-by-step explanation:

$f(x)=7x^2-5x+3,\ g(x)=2x^2+4x-6\\\\A:\\f(x)+g(x)=(7x^2-5x+3)+(2x^2+4x-6)\\f(x)+g(x)=7x^2-5x+3+2x^2+4x-6\qquad\text{combine like terms}\\f(x)+g(x)=(7x^2+2x^2)+(-5x+4x)+(3-6)\\f(x)+g(x)=9x^2-x-3$

$B:\\f(x)-g(x)=(7x^2-5x+3)-(2x^2+4x-6)\\f(x)+g(x)=7x^2-5x+3-2x^2-4x+6\qquad\text{combine like terms}\\f(x)-g(x)=(7x^2-2x^2)+(-5x-4x)+(3+6)\\f(x)+g(x)=5x^2-9x+9$

$C:\\g(x)-f(x)=(2x^2+4x-6)-(7x^2-5x+3)\\g(x)-f(x)=2x^2+4x-6-7x^2+5x-3\qquad\text{combine like terms}\\g(x)-f(x)=(2x^2-7x^2)+(4x+5x)+(-6-3)\\g(x)-f(x)=-5x^2+9x-9$

10 + 6x + 2x - 7 = 35<br> Help me pls and ty

lutik1710 [3]

Answer:

<h2><em><u>x = 4</u></em></h2>

Explanation:

10 + 6x + 2x - 7 = 35

Add Similar Elements: 6x + 2x = 8x

10 + 8x - 7 = 35

Group Like Terms

8x + 10 - 7 = 35

Subtract: 10 - 7 = 3

8x + 3 = 35

Subtract 3 From Both Sides

8x + 3 - 3 = 35 - 3

Simplify

8x = 32

Divide Both Sides By 8

8x / 8 = 32 / 8

<h2><u><em>x = 4</em></u></h2>

Help plz I don't understand and SHOW ME HOW YOU GOT IT!!!!!!!!

AysviL [449]

(48-7)x(56+19)
First of all you need to work out the brackets.
48-7=41
56+19=75
This turns the question to: 41x75
When multiply decimals you can split the numbers up into the tens and units.
40x70=2800
40x5=200
1x70=70
1x5=5
2800+200+70+5= 3075
This answer would be 3075.
