A cell boat sale has three sides that are all the same links. Each side measure x-10. The sails perimeter is 63 units PLEASE HELP QUICKLY

Answers

Answer 1

Answer:

Answer:

x=31

Step-by-step explanation:

x-10+x-10+x-10=63 (equation)

3x-30=63 (combine like terms)

3x=93 (combine like terms again)

x=31 (divide both sides by 3)

What is 402 rounded to the nearest ten

Answers

402 rounded to the tenth
4 would be your hundredth
0 would be your tenth
2 would be your ones
if your trying to figure out the tenth because it's a zero, it will still be zero
your answer is 0

2+2=5 does anyone know how that is and don't say it isn't I want to see what you say

Answers

Actually I have no clue maybe because they arent smart or wasn't thinking straight at the time.

2 + 2 = 4

2 + 2 = 5 is simply impossible and illogical!!

Perhaps maybe if it were part of a bigger & more complex equation and somehow 2 = 3, THEN it would make sense.

Answer: K

Step-by-step explanation:

Compare the equations of: h = -t² + 4t + 5 and h = -t² + 4t + 12

h = -t² + 4t + 5:

c-value is 5
⇒ h-intercept is 5

intercept form: h = -(t + 1)(t - 5)
⇒ intercepts are t = -1 and t = 5

vertex form: h = -(x - 2)² + 9
⇒ vertex is (2, 9)
⇒ maximum value of h is 9

h = -t² + 4t + 12:

c-value is 12
⇒ h-intercept is 12

intercept form: h = -(t + 2)(t - 6)
⇒ intercepts are t = -2 and t = 6

vertex form: h = -(x - 2)² + 16
⇒ vertex is (2, 16)
⇒ maximum value of h is 16

The only value that changed between these two equations is "c", however the h-intercepts, maximum values, and t-intercepts are all different.

This is because the c-value shifted the entire parabola up. Shifting the parabola up or down will affect the intercepts and the maximum value of the vertex.

Answer:

I only

Step-by-step explanation:

given h = - at² + bt + c

the vertex = - $(b)/(2a)$
