So you have 2 identical big triangles with the h = 5.75 and b = 4:
A=(1/2)bh=(1/2)*4*5.75=11.5
11.5*2=23
Then you have to smaller identical triangles with the h =2 and b=(4+4-4)/2=2
A=(1/2)*2*2=2
2*2=4
Then you have a rectangle:
A=bh=4*2=8
Add all the calculated areas:
A=23+4+8=35
The area of the shape is therefore 35 cm^2
Hope that helped.
The x-intercept is (0.143,0)
The y-intercept is (0,-2)
Answer:2*2=4
4^3=4*4*4=64
Step-by-step explanation:
Answer:
B. 143
Step-by-step explanation:
11 b
----- = -------
12 156
using cross products
11 * 156 = 12 b
divide by 12
11 * 156/12 = b
11 * 13 = b
143 = b
