Please factor 4n + 4 x 2

Answer:

m=7 z=-12

Step-by-step explanation:

expand brackets:

8m+24=5m+45

Change sides:

8m-5m=45-24

3m=21

m=7

z-6    =  3

2z         4

Coss multiply:

4z-24=6z

4z-6z=24

-2z=24

Divide both sides by -2:

z=-12

Answer:

y=2x+5

Step-by-step explanation:

The slope-intercept form of a linear equation is:

y=mx+b

Where m is the slope and b is the y-intercept.

We can start by finding the slope...

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We can use any two x, y pairs to solve for the slope. In this case let's use (0,5) and (2,9)...

[tex]Slope=\frac{9-5}{2-0}=\frac{4}{2}=2[/tex]

The y-intercept is where the line intersects the y-axis. This means that the x value is 0. In the table we can see when the x value is 0, the y value is 5 meaning the y-intercept is 5...

y=2x+5

Answer:

Their angles are equal and the sides are the same ratio

Answer:

4k - 8

Step-by-step explanation:

Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.

Hope this helps!

Answer:

dimensions: 8 ft x 8 ft      ║       32 ft of  fence she used.

Step-by-step explanation:

as its a square, its formula for area: length²

using the formula:

length² = 64

length = √64

length = 8 ft

→ The dimensions of the kennel is 8 ft x 8 ft

Using the length, we can find; how many fencing she used:

formula used: 2 ( length + length )

using the formula:

2 ( 8 + 8 )

2 ( 16 )

32 ft

Answer:

The constant of proportionality is [tex]k=\frac{7}{9}[/tex]

Step-by-step explanation:

Recall that the equation for direct variation is [tex]y=kx[/tex] where [tex]y[/tex] varies directly with [tex]x[/tex] and [tex]k[/tex] is the constant of proportionality.

Here, [tex]k=\frac{7}{9}[/tex] since [tex]2(\frac{7}{9})=\frac{14}{9}=1\frac{5}{9}[/tex], [tex]3(\frac{7}{9})=\frac{21}{9}=2\frac{3}{9}[/tex], and so on.

Answer:

Option B

Step-by-step explanation:

Given the following question:

[tex]5^2\times5^4[/tex]

In order to find the answer, we simply apply the exponent rule and add the exponents.

[tex]5^2\times5^4[/tex]
[tex]2+4=6[/tex]
[tex]=5^6[/tex]

The answer is option B or "5^6."

Hope this helps.

Answer:

120/97

Step-by-step explanation:

When you're turning a mixed fraction into an improper fraction, you keep the denominator (bottem number) the same, but you times the numerator (top number) by the whole number (non-fraction number/left number)

6 * 20 = 120

Therefore it should be 120/97

This can not be simplified though (if I recall)

180 = 132 + x + x

180 - 132 = 2x

48 = 2x

x = 24⁰

[tex]\qquad \qquad\huge \underline{\boxed{\sf Answer}}[/tex]

Let's use Angle sum property of a triangle ~

[tex]\qquad \sf  \dashrightarrow \: x + x + 132 \degree = 180 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 2x + 132 \degree = 180 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 2x = 180 \degree - 132 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: 2x = 48 \degree[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 48 \degree \div 2[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 24 \degree[/tex]

Answer:

37.5%

Step-by-step explanation:

let 15 is X % of 40,

now,

x% of 40 =15

or,X/100 ×40 =15

or,X=(15×100)/40

or,X=1500/40

orX=37.5%
