Answer:
m = 7
Step-by-step explanation:
3m + 8 + m = 36 , that is
4m + 8 = 36 ( subtract 8 from both sides )
4m = 28 ( divide both sides by 4 )
m = 7
Answer:
12 
Step-by-step explanation:
Length of first leg of a Right angle triangle= 4 centimeters
Length of second leg of a Right angle triangle= 6 centimeters
We have to find the area of tiles
Area of tiles= Area of Right angle triangle
Area of a right angle triangle=
× base × Height
Area of a right angle triangle=
× 4×6
Area of a right angle triangle=12 
Hence , the correct answer is 12 
Answer:
x = 
Step-by-step explanation:
- 18 + 64 = 0
+ 46 = 0
= - 46
x = 
Answer:
sail a = 81ft²
sail b base = 12ft
Step-by-step explanation:
question 5:
the measurements for sail A are 18ft(height) and 9ft (base)
the formula to find the the area of a triangle is (b · h) 1/2
(9 · 18) 1/2 = (162) 1/2 = 81
so ahmad will need 81ft² of fabric for sail a
question 6:
we know that the formula to find the area of a triangle is (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.
(b · 18) 1/2 = 108
= 108/ 1/2
(b · 18) = 216
18b = 216
18b/18 = 216/18
b= 12
check your work:
(12 · 18) 1/2 = 108
(216) 1/2 = 108
108 = 108 true!
the base measurement for sail b is 12ft
hope this helps and have a great day!!
