Find the area of the figure.

Area=105

Step-by-step explanation:

If we were to close the rectangle it would be 15ft x 8ft which equals 120ft

but then we'd have to find the area of the small rectangle inside being

3ft x 5ft = 15 ft

So, we'd have to subtract 15 ft from 120 ft giving us the answer of 105 ft

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
