Answer:
about 77 cm^2
Step-by-step explanation:
From 3 sides, the area of a triangle is conveniently calculated using Heron's formula:
A = √(s(s -a)(s -b)(s -c))
where s is the semi-perimeter: s = (a+b+c)/2.
For the given values of a, b, c, we have ...
s = (a+b+c)/2 = (18 +11 +14)/2 = 21.5
A = √(21.5·3.5·10.5·7.5) = √5925.9375
A ≈ 76.9801 . . . cm^2
The area is about 77 square centimeters.
Answer=65 pairs of shoes
Given the data, the following equation can be made where x is equal to the number of shoes sent to the outlet mall.
845=4x+4x+4x+x
845=13x
divide both sides by 13
65=x
65 pairs of shoes were sent to the outlet mall
Answer:
Step-by-step explanation:

Step 1: Subtract 4 form both sides
Step 2: Multiply both sides by (-3). when we are multiplying by (-3) the < will change to >.

Answer:
7m = 50.75
Step-by-step explanation:
5m=36.25
We can solve this for m by dividing each side by 5
5/5m=36.25/5
m = 7.25
We want to find 7m
7(7.25) = 50.75
