Question

Help on bothering please !!!!!reaangie nas perimeter

Answer 1

Answer:

6) F

7) B

Step-by-step explanation:

6)

$\boxed{perimeter \: of \: rectangle = 2(length + breadth)}$

60= 2[½(n -6) +2n +5]

Expand:

60= 2(½)(n -6) +2(2n) +2(5)

60= n -6 +4n +10

Simplify:

60= 5n +4

Minus 4 on both sides:

5n= 60 -4

5n= 56

Divide both sides by 5:

n= 56 ÷5

n= 11.2

Thus, option F is correct.

7)

$\boxed{area \: of \: rectangle = length \: \times breadth}$

13q +2= 9(q +6)

Expand:

13q +2= 9q +54

Bring q terms to one side, constant to the other:

13q -9q= 54 -2

Simplify:

4q= 52

Divide both sides by 4:

q= 52 ÷4

q= 13

Thus, option B is correct.
