3. A landscape plan includes a rectangular flower bed that is surrounded the wood planks. In the drawing, the rectangular flower bed is 8 in. by 12 in. The length and width of the actual flower bed will be 26 times larger than the length and width in the drawing. (a) What is the perimeter of the drawing? Show all calculations that lead to the answer and include units.
(b) What is the perimeter of the actual flower bed? Show all calculations that lead to the answer and include units.
(c) What is the effect on the perimeter of the flower bed with the dimensions are multiplied by 26? Write the final answer in a sentence and show supporting calculations to arrive at the answer.

I dont know if this is right but

A: 384 in.

B: 1040 in. = 86 ft

C: because the dimensions are multiplied by 26 inches, the perimeter for the actual flower bed is converted into feet.

Step-by-step explanation:

A: (8*2)+(12*2) = 384 in.

B: ((8*26)*2)+((12*26)*2) = 1040 in. = 86 ft.

(c)What is the effect on the perimeter of the flower bed with the dimensions are multiplied by 26? Write the final answer in a sentence and show supporting calculations to arrive at the answer.

(A)8+8+12+12=

40in = 3ft 4in

(B)8 x 26= 208

12 x 26= 312

(208 x 2) + (312 x 2) = 1040in = 86ft

Answer from: Quest

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

5c+2< 27 i really do not understand this.
