Hi! I'm happy to help!
A square root, means:
√x=y
This means that:
x=y·y=√x·√x
When we have the square button, it causes everything to be multiplied by itself once.
√x²=x
Due to the fact that the squared symbol is outside of the parenthesis, it causes both the square toot of 2, and the square root of 3, to be squared.
Now that we know this, √2², and √3²= 2, and 3.
This is why we get 2+3.
2+3=5, which is pretty self explanatory.
I hope this was helpful, keep learning! :D

the perimeter of a rectangular tray is 60in the length of the tray is double the width of a tray determine the dimensions of the rectangular tray
Answer:
Step-by-step explanation:
Width = w
Length = double the width = 2*w = 2w
Perimeter of rectangular tray = 60 in
2*(length + width) = 60
2*( 2w + w) = 60
2*3w = 60
6w = 60
Divide both sides by 6
w = 60/6
w = 10 in
length =2w = 2*10 = 20
length = 20 in
Width = 10 in

Oh and made 60% of the shots he attempted during his hockey practice he made 18 shots how many shots did Owen attempt during his hockey practice
Answer:
Owen attempted a total of 30 shots.
Step-by-step explanation:
Let's Owen's total number of attempted shots be S.
He made 60% of his total shots, which is 18. In other words, 60% of S is 18:
[tex]0.6S = 18[/tex]
Solve for S:
[tex]\displaystyle S = \frac{18}{0.6} = 30[/tex]
In conclusion, Owen attempted a total of 30 shots.

Angel got a job at in-n-out burger. He works 20 hours a week and makes $15.75 an hour. How much will his
paycheck be after 2 weeks of work (before uncle sam takes away taxes
Multiply hours per week by hourly pay rate:
20 x $15.75 = $315.00 per week
Multiply by 2 weeks:
$315 x 2 = $630
After 2 weeks paycheck is $630
Answer:
630
Step-by-step explanation:
15.75 x 20 = 315
315 is how much Angel makes in one week
315 x 2 = 630
630 is how much he will make in two weeks
The 2 signifies how many weeks have been worked

a. Explain how to add two integers with the same sign.
b. Explain how to add two integers with different signs.
Answer:
a) To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.
b) To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

Answer:
f(- 10) = 74
Step-by-step explanation:
To find f(- 10) , substitute n = - 10 into f(n) , that is
f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74
Hello there!
We are given a function below:
[tex] \displaystyle \large{f(n) = - 7n + 4}[/tex]
To find f(-10), substitute n = -10.
[tex] \displaystyle \large{f( - 10) = - 7( - 10) + 4}[/tex]
Evaluate the f(-10)
[tex] \displaystyle \large{f( - 10) = 70 + 4}[/tex]
Recall
Negative × Negative = PositiveTherefore,
[tex] \displaystyle \large{f( - 10) = 74}[/tex]
f(-10) = 74

A regular square-based pyramid has a surface area of 33 m2. If its triangular faces have an area of 6 m2, what is the length of the base of the pyramid?
Answer:
First we can do 33 time 6
Step-by-step explanation:
The length of the base of the pyramid is 3 meters.
What is a square pyramid?A pyramid is a polyhedron that has a base and 3 or greater triangular faces that meet at a point above the base. A square pyramid is a pyramid with a square base, four triangular sides, five vertices, and eight edges.
For the given situation,
The surface area of the pyramid = 33 m^2
Area of triangular faces = 6 m^2
Let the base of the pyramid be b and the height be h.
The formula of area of triangle is
[tex]A = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6 = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6(2) = (b)(h)[/tex]
⇒ [tex]12 = (b)(h)[/tex]
The formula of surface area of square pyramid is
[tex]SA = b^{2}+2bh[/tex]
⇒ [tex]33=b^{2} +2(12)[/tex]
⇒ [tex]33-24=b^{2}[/tex]
⇒ [tex]b=\sqrt{9}[/tex]
⇒ [tex]b=3[/tex]
Hence we can conclude that the length of the base of the pyramid is 3 meters.

Find the area for all of these numbers
Answer:
The Answer is 29cm
Step-by-step explanation:
The area of this shape is made from two shapes.
Shape one is a rectangle with the dimensions 2cm by 4cm
2x4 = 8
So the area of rectangle 1 is 8
The other rectangle has the dimensions 4cm by 7cm
Because you have to account for the other triangle not being there (solved)
4x7 = 21
21+8
29cm
