Answer:
86 m²
Step-by-step explanation:
It can be convenient to think of the figure as an 8×12 rectangle with a 4×5 triangle cut off the corner.
The rectangle area is the product of its length and width:
(12 m)×(8 m) = 96 m²
The triangle area is half the product of its base and height:
(1/2)(4 m)(5 m) = 10 m²
Then the area of the figure is the difference of these:
96 m² -10 m² = 86 m²

Step-by-step explanation:
Answer:
n = 10
Step-by-step explanation:
Solve for n:
(3 n)/5 = 6
Multiply both sides of (3 n)/5 = 6 by 5/3:
(5×3 n)/(3×5) = 5/3×6
5/3×3/5 = (5×3)/(3×5):
(5×3)/(3×5) n = 5/3×6
5/3×6 = (5×6)/3:
(5×3 n)/(3×5) = (5×6)/3
(5×3 n)/(3×5) = (3×5)/(3×5)×n = n:
n = (5×6)/3
6/3 = (3×2)/3 = 2:
n = 5×2
5×2 = 10:
Answer: n = 10
Answer:
#4 is not always true, only when it's a square.
Answer:
x = 14
Step-by-step explanation:
X / 2 = 7
Multiply by 2 to isolate x.
x = 7 * 2
x = 14
