The figure shown is created by joining three rectangles. Enter the area of the figure, in square centimeters. Round to the neare

Basile [38]

Answer:

235

Step-by-step explanation:

first, separate the floor into 3 different rectangles to calculate the area and then add them together.

area of rec=L*B

rec 1: 9*12.5=112.5

rec 2: (13.5-5.5)*(19.5-9-7)=28

rec 3:7*13.5=94.5

Then:

112.5+28+94.5=235

A dilation has center (0, 0). Find the image of each point for the given scale factor.

pshichka [43]

Answer:

A. (−3,5)

Step-by-step explanation:

The rule for dilation by scale factor k is given by:

$(x,y)\to (kx,ky)$

The given point is P(-3,5) and the scale factor is k=1

We substitute the point and the scale factor into the rule to get:

$P(-3,5)\to P'(-3\times1,5\times1)$

This gives us:

$P(-3,5)\to P'(-3,5)$

The correct answer is A
