Answer:
40 cm^2.
Step-by-step explanation:
Area = the sum of the 2 triangles
= 1/2 * 6 * 8 + 1/2 * 4 * 8
= 24 + 16
= 40 cm^2.
Answer:
(x, y, z)
(5,-2,3)
Step-by-step explanation:
try plugging those into the equation.
just to make sure I was correct.
Answer:
C(C^3 + 8C^2 -3C -7)
Step-by-step explanation:
(-3C^4-5C^2-7C)+(4C^4+8C^3+2C^2)
(-3C^4 +4C^4)+8C^3 + ( -5C^2 +2C^2) -7C [Combine like terms]
C^4 + 8C^3 -3C^2 -7C [Simplify]
C(C^3 + 8C^2 -3C -7) [Isolate 1C from the rest]
2x + 15 = 3x
-2x -2x
15= x
the measure of angle 5 is 15 I believe
do you have a picture of the problem to see if I'm correct?
