I need help please . 2nd box is multiply choose.
love history [14]

Answer:

First box = 22.5, 45/2, or 22 and 1/2

Second box = square inches (because area is always ^2, or squared)

Step-by-step explanation:

A = B * H

B = base

H = height

Base = 5 inches

Height = 4.5 inches

5 inches * 4.5 inches = 22.5 inches^2

This can also be written as 45/2 or 22 and 1/2

I hope I helped!

Part A: The area of a square is (4x^2 - 12x + 9) square units. Determine the length of each side of the square by factoring the
AlexFokin [52]

Answer: Area = side²

If Area = 4x² + 12x + 9, then the side is the √(4x² + 12x + 9)

Let’s factor 4x² + 12x + 9

What two numbers multiply to be 36 (which came from 4 * 9) add up to be 12?

6 and 6 are the two numbers, because 6 * 6 = 36, and 6 + 6 = 12.

We can break 4x² + 12x + 9 into (4x² + 6x) + (6x + 9)

Factor 4x² + 6x, the greatest common factor is 2x, so the 2x goes on the outside, leaving us with 2x + 3 on the inside, so that gives us 2x * (2x + 3).

Factor 6x + 9, the greatest common factor is 3, so the 3 goes on the outside, leaving us with 2x + 3 on the inside, that gives us 3 * (2x + 3).

Now we have the 4x² + 12x + 9 written as 2x (2x + 3) + 3 (2x + 3). Since we now have a common factor, 2x + 3, we can combine them by adding 2x (2x + 3) + 3 (2x + 3) as like terms, so we now have (2x + 3) * (2x + 3).

We can simplify (2x + 3)(2x + 3) into (2x + 3)².

There. The simplest factored form of 4x² + 12x + 9 is (2x + 3)²

Ok, the Area = (2x + 3)²

Let’s solve for the side

(2x + 3)² = side²

square root both sides and take the positive root

side = √(2x + 3)²

side = 2x + 3

The side length is: 2x + 3 units

I hope you get a good grade lol :)

Help me please edddd
nydimaria [60]

Answer:

the second one 9v+36

Step-by-step explanation:

because with the way it set up it wants you to multiply 9 by everything inside of the parenthesis so 9 times v is 9v and 9 times 4 is 36 thus 9v+36 and you also take the addition symbol from inside the parenthesis.

Brenda finish 1/3 of a friendship bracelet 1/2 of an hour at this rate how many bracelets can she finish in 1 hour
Tresset [83]

First, 1/2 of an hour is 30 minutes. Well, how many 30 minutes are in an hour? 2, because 2*30 = 60.

So Brenda finish 1/3 of the bracelet in 30 minutes. We would just do...

(1/3)*2 = 2/3

Brenda can finish 2/3 of a bracelet in 1 hour.
