Given polygon DEFGH ≅ polygon QRSTU . What is the measure of ∠R ? Enter your answer in the box. m∠R = ° An irregular pentagon with vertices labeled D E F G and H. Angle D measures 60 degrees. Angle E measures 143 degrees. Angle F has a right angle symbol. Angle G measures 102 degrees. Angle H measures 145 degrees. A second irregular pentagon with vertices labeled Q R S T and U.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
