There should be a horizontal line at where y=4. everything in the bottom left between the lines should be shaded
Sin(A-B) = sinAcosB - cosAsinB
=<span>sin23cos27- cos23sin27</span>
= sin(23-27)
= sin(-4)
=-sin4
Answer:
Step-by-step explanation:
A = 4 ft
B = 10 ft
C = 8 ft
D = 6 ft
b) Area of rectangle = length * width
Area of 2 triangle = base * height
Area of right triangular prism = area of 2 triangles +area of left rectangle + area of middle rectangle + area of right rectangle
= 6 * 8 + 4* 6 + 4 * 10 + 4 * 8
= 48 + 24 + 40 + 32
= 144 ft²
A, you combine like terms.
a) 11n-4+n+12
11n+n=12n
-4+12=8
12n+8
