Answer:
ok so
Step-by-step explanation:
plug it in
since x=5
it would be 5=3×5-9
which would give us 5=6x
Subtract
x=-1
luisa is building a sand box in her backyard. she places four pieces of wood in a rectangle to form the frame. the rectangle is 4 feet long and 3 feet wide. how can she use a measuring tape to make sure that the corners of the frame will be right angles?
Answer:
As we know rectangles have 90 degree angles at all 4 of its corners.
In this question we know that the length is 4 feet while the bredth is 3 feet.
Therefore to solve this answer we can use the Pythagoras theorm.
By Pythagoras:
[tex]4^{2} + 3^{2} = diagonal^{2}[/tex]
Therefore the diagonal must be 5 feet
So if Luisa measures the diagonal with a tape and it measures 5
Then it proves that all 4 corners due have 90 degree angles

The polygons are similar. Find the value of x.
Answer:11
Step-by-step explanation:
Which choice is similar to the figure shown?
Please help I’m confused on what to do.
The top left figure is similar with the figure given in this problem.
What are similar figures?Two figures are defined as similar triangles when they share these two features listed as follows:
Congruent angle measures, as both triangles have the same angle measures.Proportional side lengths, which helps us find the missing side lengths.Hence the top left figure is similar with the figure given in this problem, as:
5/2 = 20/8.The angle measures are the same.More can be learned about similar figures at brainly.com/question/14285697

solve for x
2 + x^2 = 18
Answer:
16
Step-by-step explanation:
Answer:
4 and -4
Step-by-step explanation:
To solve, just isolate x
2+x^2=18
subtract both sides of the equation by 2
x^2=16
find the square root of 16
(remember, no matter if a number is positive or negative, if it is squared, it automatically becomes positive)
to get:
x=4
and
x= -4

Matt decides the length of his table will be 15 in. He calculates that the area of the table is 30 in. squared. Determine if Matt’s calculation is correct
Answer:No Matt's calculation is not correct.
Step-by-step explanation:
We have to multiply by the number of the area.If it is 4 inches we multiply by 4
15 x 4 =60
A=4 inches squared
A=LxW (length x width )
so you can say that:
Matt is incorrect because He skipped the step of multiplying 2 by 2 in the formula which is where we get 4 from.

whats the distributive property
Answer:
5n + 5a
Step-by-step explanation:
This would be your simplified algebra expression.
Answer:
The distributive property tells us how to solve equations in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. Normally when we see an equation like this … 4(8+3) distributive property format 4(8+3) -> 4(11) -> 44 we just evaluate what’s in the parentheses first, then solve it: 4(8+3)=4x8 + 4x3=44 These are the 2 methods

Step-by-step explanation:
George bought a model of a Viking ship for $68. If he paid
$5.10 in sales tax, what was the sales tax rate?
Answer:
We can convert 6.75% to a decimal by dividing by 100.
If x is the price of the house, then the sales tax is 0.0675x. The price of the house and the sales tax add up to $319,000.
x+0.0675x=319,000
Combe terms on the left.
1.0675x=319,000
Finally, divide both sides by 1.0675.
x=319,0001.0675=298,829.04

Answer:
[tex]slope = 1 [/tex]
Step-by-step explanation:
We can see that the graph cuts the x axis at , (-1,0) and y axis at (0,1) . So we can find the slope as ,
[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\implies slope = \dfrac{ 1-0}{0+1} \\\\\implies\boxed{\boxed{ slope = 1 }}[/tex]
