Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

l = 9 cm

w = 6 cm

Substitute the values into the above formula and solve

We have

P = 2(9) + 2(6)

= 18 + 12

We have the final answer as

Hope this helps you

Answer: d.30cm

Step-by-step explanation:

the formula for perimeter is P=2L+2W

Substitute the length and width

P= 2(9)+2(6)

Multiply

P= 18+16

Add

P=30

Add the unit

P= 30cm

Explanation:

We're given that f(x) = x^2

The function g(x) is vertically stretched to be five times taller. We see this with the point (1,5) on the purple graph since its counterpart is at (1,1) on the blue graph.

We look at how the y values changed. So we had gone from y = 1 to y = 5. This jump means "multiply by 5"

If we do this to all the y values on the blue graph, then all the points jump to a height 5 times taller. Something like (2,4) moves to (2,20). Something like (3,9) goes to (3,45). And so on. This is what produces the purple g(x) graph.

You could say that

g(x) = 5*f(x)

g(x) = 5x^2

This works because y = f(x), so when we say 5*f(x), we really mean 5*y.

Answer:

Step-by-step explanation:

2q + 2p = 1 + 5q

-3q + 2p = 1

-3q = 1 - 2p

3q = 2p - 1

q = (2p -1)/3

Answer:

The measure of x = 45 degrees

Answer:

x is equal to 50.

Explanation:

The three lines intersect creating a triangle. All angle measures for triangles in Euclidean geometry must have a sum of 180 degrees. Because of the Vertical angles theorem, which states if two angles are opposite they are congruent, this means the angle across from 40 degrees is also 40 degrees. Since we know that the second angle is 90 degrees based on the right angle sign. By adding 40 and 90 you get a sum of 130. Now you subtract 130 from 180. This gives you 50 degrees. Since the Vertical angle theorem states two opposite angles are congruent we know the x is equal to 50 degrees.

Answer:

n = -5

Step-by-step explanation:

Step 1: Write equation

-n + 7 - 2n + 5n - 3 = -6

Step 2: Solve for n

Combine like terms: 2n + 4 = -6

Subtract 4 on both sides: 2n = -10

Divide both sides by 2: n = -5

Answer:

1/3

Step-by-step explanation:

The most important thing to remember is that the poster is divided into three equal parts and 1 part of it is for his neighborhood friends and another one part of it is for his friends from school. The denominator would be three and the numerator would be the 1 part he uses for his friends from school.

Answer:

Step-by-step explanation:

g(x^2 + 2x - 4)

3(x^2 + 2x - 4) + 1

3x^2 + 6x - 12 + 1

3x^2 + 6x - 11

Answer: 12

Step-by-step explanation: 6 times 2 is 12 and she has a 6 inch string and each peace is 1/2 inch long so she would have 12 peaces of string.

Answer:

Answer:

-11

Step-by-step explanation:

Answer:

[tex]x=-11[/tex]

Step-by-step explanation:

[tex]-1=\frac{\left(5+x\right)}{6}[/tex]

Switch sides:

[tex]\frac{\left(5+x\right)}{6}=-1[/tex]

Multiply both sides by 6:

[tex]\frac{6\left(5+x\right)}{6}=6\left(-1\right)[/tex]

[tex]5+x=-6[/tex]

Subtract 5 from both sides:

[tex]5+x-5=-6-5[/tex]

[tex]x=-11[/tex]

Answer:

Answer:

x = 7

Step-by-step explanation:

0 = 4(x+5) + 8

expand:

0 = 4x + 4*5 + 8

0 = 4x + 20 + 8

0 = 4x + 28

simplify

4x = 28

simplify

x = 28 / 4

x = 7

Answer:

Substitution

Step-by-step explanation:

Subtitue x=3 into the second equation

y=7

Answer:

grams

Step-by-step explanation:

Steps to solve:

f(x) = 14 - 0.5x when x = 30

~Substitute

f(30) = 14 - 0.5(30)

~Simplify

f(30) = 14 - 15

~Subtract

f(30) = -1

Best of Luck!

Answer:

You can tell 7.360 and 7.36 are equivalent decimals because when you put a zero in the decimal places, it doesn't count as a number and it doesn't have a value. In conclusion, zero is just a placeholder. Therefore, if you have the zero or not it doesn't matter.

Answer:

7:21   For every student wearing a blue shirt, there were 3 students wearing red shirts.

Step-by-step explanation:

If there are 28 students and 7 are wearing blue shirts then the number of students wearing red shirts is 28 - 7 = 21 so 21 students are wearing red shirts.

That means the ratio of blue shirts to red shirts is 7:21

That also means that for every student wearing a blue shirt, 3 were wearing a red shirt.

We get this because 21/7 = 3  and 7/7 = 1

Answer:

$256

Step-by-step explanation:

240/100*20=48 so then 15m of cloth is $192. To get too 20m you can divide 15 by 3 and then times it by 4. 192/3*4=256. Therefore for 20 metres of cloth it is $256. YAY
