Start at positive 10.

When adding a negative number move that many places to the left, so from positive 10 move 5 places to the left to get the answer which is positive 5

Answer:

11. b = 30

Step-by-step explanation:

a^{2} + b^{2} = c^{2}

Substitute

16^{2} + b^{2}  = 34^{2}

256 + b^2 = 1156

b^2 = 1156-256\\b^2 = 900

b = \sqrt{900}

b = 30

Your welcome and don't forget to say <u>Thanks</u>

A trapezoid has a perimeter of 14 feet. What will the perimeter be if each side length is increased by a factor 7? 21 feet 98 fe
natka813 [3]

Answer:

Correct choice is B

Step-by-step explanation:

Let a, b, c and d be the trapezoid's sides lengths.

The perimeter of the trapezoid is the sum of all sides lengths, thus,

a+b+c+d=14\ ft.

If each side length is increased by a factor 7, then new sides have lengths 7a, 7b, 7c and 7d. The perimeter of new trapezoid is

7a+7b+7c+7d.

Use the distributive property for this expression:

7a+7b+7c+7d=7(a+b+c+d).

Since a+b+c+d=14\ ft, then

7a+7b+7c+7d=7(a+b+c+d)=7\cdot 14=98\ ft.
