Answer:
63
Step-by-step explanation:
k=y/x
y/x=k
y=k×x
y=7×9
y=63
The sum of the angles of a quadrilateral is 360°.

Given that x=30, the measure of ∠C is
∠C = (5/2)×30 +40 = 115
The appropriate choice is ...
D) 115°
27/64 . because you do 3/4 to the third power (3x) which gives you that
Answer: Yes. (gof)(0) = -5
(gof)(0) means you will find the function of g(f(0)), which means we will find f(0) and plug that value in for x in the function g(x)
We know f(0) is -1, so we can plug -1 into the equation of g(x)
(gof)(0) = (-1) - 4
(gof)(0) = -5
The area of a triangle is 1/2 b/h. So what you do is you find base and height, multiply them together and whatever answer you got, you divide by 2.
Example:
A= 1/2 (b x h)
A= 1/2 (4 x 6)
A= 1/2 (24)
A= 12
Hope this helps!
