Answer: 7x + 261

Step-by-step explanation:

(5x + 252 + x + 5) + (x + 4)

5x + 252 + x + 5 + x + 4 (get rid of parenthesis)

7x + 261 (combine like terms)

Kitty [74]

Answer:

$a+b+c=32$

Step-by-step explanation:

we have

$(-2x^{2} +x+31)+(3x^{2}+7x-8)$

Adds the terms

Group terms that contain the same variable

$(-2x^{2}+3x^{2})+(x+7x)+(31-8)$

Combine like terms

$(x^{2})+(8x)+(23)$

where

$a=1,b=8,c=23$

therefore

$a+b+c=1+8+23=32$

Please help !! Use Pythagorean theorem :) and show your work if you can thanks :”) will give b

g100num [7]

Answer:

$b=\sqrt{1575}$ ≈ 39.7ft

Step-by-step explanation:

The Pythagorean theorem:

$a^{2}+ b^{2}= c^{2}$

(a and b are the two shorter legs and c is the largest leg, which is also the opposite side of the right angle)

First, the value of a and c is given. So, we can go ahead and plug those value in and then solve for b.

$45^{2}+ b^{2}= 60^{2}$

$2025+b^{2} =3600$

To find b, we have to get it by itself. So we subtract 2025 from both sides then square root both sides. Resulting in:

$b^{2} =1575$

$b=\sqrt{1575}$ ≈ 39.7ft

How do we do Systems of Equation and then how do we label it as one solution, no solution, or infinitely many solutions.

RoseWind [281]

To solve Systems of Equations you can use graphing, substitution, or by adding, subtraction, multiplying, or division methods. One solution is consistent and dependent. No solution is inconsistent. Infinitely many solutions is consistent and dependent.
