Answer:

see explanation↓

Step-by-step explanation:

(a)

$(3x+2)-(x+5)=3x+2-x-5$

$(3x+2)-(x+5)=2x-3$

ANSWER: Linear binomial

(b)

$(3x+8)+(4x^{2}-x)=3x+8+4x^{2}-x$

$(3x+8)+(4x^{2}-x)=4x^{2} +2x+8$

ANSWER: Quadratic trinomial

(c)

$(x^{2}+7x)-(x^{2}+5)=x^{2}+7x-x^{2}-5$

$(x^2+7x)-(x^2+5)=7x-5$

ANSWER: Linear binomial

(d)

$(2x+8)+(3x^2-2)=2x+8+3x^2-2$

$(2x+8)+(3x^2-2)=3x^2+2x+6$

ANSWER: Quadratic trinomial

(e)

$(x^2+5x-2)+(8-5x)=x^2+5x-2+8-5x$

$(x^2+5x-2)+(8-5x)=x^2+6$

ANSWER: Quadratic binomial

What percent of 99 is 90?

Yuri [45]

Answer:

91%

Step-by-step explanation:

We can use the formula $\frac{is}{of}=\frac{percent}{100}$

"is" is 90
"of" is 99
"percent" is what we are solving for so we will denote it as x

Substituting in our values we get $\frac{90}{99}=\frac{x}{100}$

We will need to cross multiply here to get (90)(100) = (x%)(99)
This simplifies to 9000 = 99x%
Dividing by 99 on both sides we get 90.9% → x = 91%

Alejandra plans to sew fringe on a scarf. The scarf is shaped rectangle. The length of the scarf is 48 inches. The width is one

aleksandr82 [10.1K]

Ok so you will be finding the perimeter of this rectangle. The formula is P(perimeter)=2L(length) + 2W(width)

so the length is 48 and the width is 1/2 of 48, and we all know that 1/2 of 48 = 24 right? so in the formula is says 2L so we will take 48 and multiply it by 2 and get 96. The same way with the width. 24 times 2 = 48 so then we add them together and get 144. Therefore the perimeter and the length of fringe that she will use (or how ever you say it) will be 144 inches.

Hope this helps!;)
