Solve for the perimeter and keep it in pi
galben [10]

Answer:

24+6pi

Step-by-step explanation:

the sides on the left and right added up are

12+12=24.

the formula for perimeter of a circle is 2πr.

3 is the radius, making the equation

2π3 which is 6 pi.

for the top semicircle, the perimeter would be 6 pi divided by 2 because its a semicircle.

the bottom cut out half would also be 3 pi.

in total, we would have 24+3pi+3pi which would lead you to 24+6pi.

What's two thirds of a straight line?
Komok [63]
Well if the straight line is equal to 1 then your answer is 2/3 but if the straight line is not equal to 1 you need to know what it is equal to or you could use the equation y = (2/3)x
"x" would be the length of the straight line and "y" would be two-thirds of it

Use a negative factor to factor the expression - 7a+49b - 35
Helen [10]

Answer:

using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)

Step-by-step explanation:

Given the expression

- 7a+49b - 35

Rewrite -35 as 5 · 7

Rewrite 49 as 7 · 7

so

= -7a + 7 · 7b - 5 · 7

as -7 is the common factor, so factoring out

= -7(a-7b+5)

Thus, using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)
