Answer:
Step-by-step explanation:
so first what you want to do is split the shape in to
Draw a line down where the 2 is.
you should have a rectangle and a triangle
then you find the area of the rectangle
Rectangle:
5 x 2 = 10m^2
After than you try to find the triangles area
the bottom of the triangle is 9m but since to split it in 2 you will now have 7m
multiple 5 times 7 and you will receive 35 then you divide that by 2 and you will have 17.5m^2
Add your two areas together and you will get 27.5m^2
(2x +3)(2x-3)= 0
x= -3/2 x = 3/2

Step-by-step explanation:
Answer:
53
Step-by-step explanation:
63-10 = 53
biggest number - smallest number = range
Answer:
B= 17.1
Step-by-step explanation:
The formula for the area of a triangle is BH1/2
The word problem gives you the area and the height
Set the problem:
369.25= 42.4(1/2)(B)
42.4(1/2)=21.2
369.25=21.2B
Divide both sides by 21.2 to isolate the variable
17.41=B
Hope this helps! :)
