Solve each equation. 8x2 - 24 = 3x2 - 9

MariettaO [177]

Ok I'm not sure on how I would do the last bit of the equation but here's what I've got;

Answer 1=                    -8 = -3

Answer2=                    -8 - 3= -11

Not 100% sure on this. so, I'm sorry if its wrong

How many square inches of sheet metal are used to make the vent transition shown? (The ends are open.)

ad-work [718]

Answer:

Area of the metal sheet required = 364 square inches

Step-by-step explanation:

Area of the metal sheet required = Surface area of the lateral sides of the vent transition

Since, lateral sides of the vent is in the shape of a trapezoid,

Therefore, surface area of the vent = 4(Surface area of one lateral side)

= $4[\frac{1}{2}(b_1+b_2)h]$

Here, $b_1$ and $b_2$ are two parallel sides and $h$ is the distance between these parallel sides.

Surface area of the vent = $4[\frac{1}{2}(8+5)14]$

= 364 square inches

Therefore, area of the metal sheet required = 364 square inches

Solve the compound inequality.

larisa [96]

Answer:

Step-by-step explanation:

9 - 4x > = 5 or 4(-1 + x) - 6 > = 2

-4x > = 5 - 9 -4 + 4x - 6 > = 2

-4x > = -4 4x - 10 > = 2

x < = -4/-4 4x > = 2 + 10

x < = 1 4x > = 12

x > = 12/4

x > = 3

answer is : B

Need help with 2,3,4

Harman [31]

Answers:

In these exercices are ilustrated the representations of the fractions

2) Firstly, we have 3 equal segments, each one representing $\frac{1}{4}$ , hence:

$\frac{3}{4}$ is 3 copies of $\frac{1}{4}$

Let's prove it, taking into account we are adding fractions with the same denominator:

$\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}$

There are 4 equal parts that make a whole

Four copies of $\frac{1}{4}$ make $\frac{4}{4}$ or 1 whole

$\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{4}{4}=1$

3) Here we have a line divided into four segments, each one of $\frac{1}{5}$ . Hence:

This is $\frac{4}{5}$ of a line. $\frac{4}{5}$ is 4 lengths of $\frac{1}{5}$

$\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}=\frac{4}{5}$

If we draw one more $\frac{1}{5}$ we will have $\frac{5}{5}$ or 1 whole.

Then:

5 lengths of $\frac{1}{5}$ make $\frac{5}{5}$ or 1 whole.

4) In this part the answer is in the attached image. If we have two equal segments, each one of $\frac{1}{3}$ we will have as a result $\frac{2}{3}$ .

If we add another $\frac{1}{3}$ segment, we will have three segments of $\frac{1}{3}$ , having as a result $\frac{3}{3}=1$
