Help! (math and area!) i'll give brainliest.

5. 12 cm

6. 50 cm

5. in

Step-by-step explanation:

5. because 6*2 equal 12 and the formula for area is length times width.

6. because 10*5 equal 50 and the formula for area is length times width.

7. because 20/4 equals 5 and the formula for the length of one side is area/width.

5. is a. 12cm. 6. is c.25cm. 7.  is c. 30 in

Step-by-step explanation:

15

step-by-step explanation:

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)(

4

)=(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.

−3x
