Answer:

82

Step-by-step explanation:

1'st step: a^{2} + b^{2}= c^{2} is the formula for the pythagorean theorem

2'nd step : 18^{2} + 80^{2} =  c^{2}

3'rd step:   324+6400 =  c^{2}

4'rd step: 6724=  c^{2}

5'th step: \sqrt{6724} =82

6'th step : therefore the value of c is 82 cm

A cylinder has a radius of 4x + 2 and a height of 5x + 4. Which polynomial in standard form best describes the total volume of t
forsale [732]
V = π r² h
V= π (4x+2)² (5x+4)
V = π (4x+2)(4x+2)(5x+4)
V = π (16x²+16x+4)(5x+4)
V= π(80x³+144x²+84x+16)
V= 251.33x³ +452.39x²+263.89x+50.27

Which number belongs to the solution set of the equation below? x - 7 = 35 A. 22 B. 28 C. 42 D. 41
TiliK225 [7]
Hey there!

To find a solution that would satisfy the value of x, the first thing you must do is to first solve for x. To solve x-7=35, you must add 7 to both sides to isolate x. This should result in x=42.

When you look at the answer choices given, notice that choice C is the solution for x, 42.

Therefore, your answer would be C. 42.

To check if this is correct, you can plug 42 back into the equation x-7=35 to see if you get a true statement:
42-7=35
35=35

Hope this helps!

Find the value of X in the parallelogram below.
nignag [31]

Answer:

28

Step-by-step explanation:

In paralellograms, the lengths of the parallel sides are equal to each other

As seen in the figure, the side that is parallel to the side that is represented with x has a length of 28 units, so the value of x is also equal to 28
