P1=2(l+w)---->(equation 1)
after the length and the width are doubled
p2=2(2l+2w)
we will take 2 common factor out of the bracket
p2=2(2(l+w))
then from equation1
p2=2p1
then the answer is the choice number c

The perimeter will grow by a factor of 2, so C is the correct answer.

How to estimate 9.1% of 59.3

gavmur [86]

Answer:

Step-by-step explanation:

For a quick rough estimate, I'd round 9.1% up to 10% and 59.3 to 60. 10% of 60 is 0.1(60) = 6.

For a more accurate estimate, round 9.1% down to 9% and 59.3 up to 60. Then 9% of 60 is 5.4.

A line passes through the points ( − 16 , 14 ) and ( 8 , 35 ) . Calculate the slope of the line - simplify answer if possible. (

REY [17]

Given two points $(x_1,y_1),\ (x_2,y_2)$ , the slope of the line connecting them is defined as

$m=\dfrac{\Delta y}{\Delta x}=\dfrac{y_2-y_1}{x_2-x_1}$

In your case, the points are

$(x_1,y_1)=(-16,14),\ (x_2,y_2)=(8,35)$

Plugging these values in the slope formula gives

$m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{35-14}{8-(-16)}=\dfrac{21}{24}=\dfrac{7}{8}$

Can someone solve this

Sloan [31]

The general equation of a line is y = mx+b. The line is horizontal and the slope (m) of a horizontal line is 0. So y = 0x + b = b. Since the y intercept (where it crosses the y axis) is -1 (or b = -1) then you have the equation y = -1.
Answer: y = -1.
