Evaluate this expression: 3(4 + 7) – 5 • 4

13

Step-by-step explanation:

3 x 11 - 5 x 4

3 x 11 - 20

33 - 20

13

13

Step-by-step explanation:

You will need to use PEMDAS for this.

First, complete what is in the parantheses (4+7=11). We will then multiply 3 to 11 and get 33 so we are left with 33 - 5 * 4. The next step in PEMDAS is multiplication so we will multiply 5*4 to get 20.

Finally, subtract 20 from 33 to get your final answer which is 13.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

b, i believe, but not sure.
