Answer:
[tex]4\sqrt{21}[/tex]
Step-by-step explanation:
Pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].
Which in this case:
'c' is hypotenuse. (hypotenuse = 20)
'a' and 'b' are the other sides. (a = x, b = 8)
[tex]a^{2} +b^{2}= c^{2}[/tex] [tex]x^{2} +8^{2} =20^{2}[/tex] [tex]x^{2} + 64 = 400[/tex] [tex]x^{2} = 336[/tex]Now we should just take square root from the both sides.
and the answer will be [tex]\sqrt{336}[/tex] or [tex]-\sqrt{336}[/tex], but a side of a triangle can not be a negative number! so the answer will be [tex]\sqrt{336}[/tex].
As you see [tex]\sqrt{336}[/tex] is not the simplest radical.
We can write [tex]\sqrt{336}[/tex] as [tex]\sqrt{16 * 21}[/tex].
And from the laws of radical we can write [tex]\sqrt{16*21}[/tex] as [tex]\sqrt{16} * \sqrt{21}[/tex].
[tex]\sqrt{16} * \sqrt{21} = \sqrt{16}\sqrt{21} = 4\sqrt{21}[/tex]
I hope it helps you. Please choose my answer as the brainliest.

1. The ratio of red marbles to blue marbles
in a bag is 2 to 5. If there are 60 more
blue marbles than red marbles in the
bag, how many marbles are there all
together?
Answers
Answer:
84
Step-by-step explanation:
Cross multiply to solve for the red marbles
Let x = the number of red marbles
2/5 = x/60
Cross multiply
2(60)/5 = x
x = 24 which is the number of red marbles.
60 blue plus 24 red = 84 total marbles.

Answers
Answer:
Step-by-step explanation:
One of the things you should keep in mind about parallel lines is that there are 8 angles in this configuration.
4 are equal to one value
and 4 other angles which are the supplements to the first four. If you know the value of one of the 8 angles, you know the value of the other seven.
So angles (8) 6 4 and 2 are all 82 degrees.
Angles 1 3 5 7 and all equal to 180 - 82 = 98
Number 8 is given as 82. It's the red number.
number 6 is vertically opposite number 8 so those two are equal
Number 6 is an alternate interior angle to 4. Those two are equal.
Number 2 is number 4s vertically opposite angle. The others are all done somewhat the same way.

The larger of two consecutive integers is 13 greater than four times the smaller. Find the integers. -3, -4 7, 8 3, 4
Answers
Answer:
The integers are -3 and -4.
Step-by-step explanation:
Two consecutive integers are an integer and the one just greater or just less than the4 first one, such as 5 and 6, or -8 and -9.
If the smaller integer is x, then the next greater integer is x + 1.
x + 1 = 4x + 13
-3x = 12
x = -4
x + 1 = -3
Answer: The integers are -3 and -4.
Check:
Smaller integer: -4
Larger integer: -3
4 times smaller integer = 4 * (-4) = -16
13 greater than 4 times smaller = -16 + 13 = -3 = greater integer
-3 and -4 is the correct answer.
Answer:
-3 and -4
They are indeed correct.

Given : The area of a square is 676 square feet. what is the perimeter of the square?
Solution :
Area of Square = 676 ft²
Let's assume the constant multiple be α (alpha)
Length × Breadth = 676α × α = 676α² = 676α = √676α = 26So, now getting perimeter
As we know that, Perimeter = 4(Side)
Perimeter = 4(26) Perimeter = 104Henceforth, the perimeter of square is 104 ft

Answer:
Pizza 1: lenght(l)=16 and width(w)=4
Perimeter=40in.
Pizza 2: l=32 and w=2
Perimeter=68in.
Step-by-step explanation:
1. List down factors of 64.
64=1,2,4,8,16,32,64
2. Select the factors you'll be using to draw your rectangles. In this case I selected the factors 2,4,16 and 32 because area of rectangle=l×w. Therefore 2×32=64 and 4×16=64.
3. Draw your rectangles according to the measurements you chose. If the drawing is too big to fit the box you can simply use a scale. Such as 1 inch=4 inches on your drawing. For example, when drawing the length of the second Pizza which is 32in. you can simply draw a line of 8 inches.
4. After drawing your pizzas you niw have to find the Perimeter of both. Simply use the formula Perimeter of a rectangle=2(l+w)
Pizza 1: Perimeter=2(16+4)
=2×20
=40in.
Now do the same for Pizza 2 using its own lengjt and width. Hope this helped.
