2. Beth covered a picture with unit squares. Each unit square is 1 square
inch. The area of Adam's picture is 12 square inches more than the area
of Beth's picture. The length of Adam's picture is 7 inches.

Beth area=16 in²

Adam width=4 in

Step-by-step explanation:

Considering the attached image, Beth's area will be 4*4=16in²

Since Adams area is 12 more then his area will be 12+16=28 in²

Since area is given as A=lw where l is length and w is width then

28=7w

w=28/7=4 in

The attached figure is used for question parts

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.
