First problem:
n/4 + 2 = -9
-2 -2
n/4 = -11
x4 x4
n = -44
Check:
-44/4 + 2 = -9
-11 + 2 = -9
-9 = -9
Second problem:
3/4x = -12
0.75x = -12
-------- ----
0.75 0.75
x = -16
3/4 * (-16) = -12 OR 0.75 * (-16) = -12
-12 = -12
Still get the same answer.
Answer:
0.88m²
Step-by-step explanation:
Area of a trapezium = 1/2(a+b)h
a and b are the parallel sides
h is the height
Given
a = 1m
b = 1.2m
h = 0.8m
Substitute
Area of the trapezium = 1/2(1+1.2)(0.8)
Area of the trapezium = 1/2(2.2)(0.8)
Area of the trapezium = 1.1 * 0.8
Area of the trapezium = 0.88m²
Answer:
32x4= 128 x 2= 256
Multiplied by two because you're adding the same equation
