Answer:
Blue Rectangle: <u>135 mm²</u>
Blue Triangle: <u>45 mm²</u>
<em>Not sure if you need this but the </em>Total Square: <u>225 mm²</u>
Step-by-step explanation:
Area of a rectangle: <u>length x width</u>
Area of a triangle:
<u> x base x height</u>
First find the area of the blue rectangle.
Length = 15 mm
Width = 9 mm
Area = 135 mm²
Now find the area of the blue triangle:
Base = 6 mm (because the bottom is 15 total and you subtract the 9)
Height = 15 mm
Area = 45 mm²

Answer:
n = -7/5
Step-by-step explanation:
Let n = number
6n = (n+3) -10
Combine like terms
6n= n-7
Subtract n from each side
6n-n=n-n-7
5n = -7
Divide by 5 on each side
5n/5 = -7/5
n = -7/5
