Answer:
The area of the figure is 61.24 cm
Step-by-step explanation:
The area for the parallelogram is determined by base x height, so 7 x 6 = 42.
The area of a circle is 
r², with r being the radius, so that means the circle area is 38.48, but because its a semicircle, its half of that, so the area is 19.24.
42 + 19.24 = 61.24
Answer:
the three numbers = -8, -32, -30
Step-by-step explanation:
let the first number = a
let the second number = b
let the third number = c
From the first statement: b = 4a
From the second statement: c = b + 2
From the third statement: b - 2c = 28
From the above equations, we can solve (1) and (2) together.
c = b + 2
b = c - 2
Also, b - 2c = 28
(c - 2) - 2c = 28
c - 2 - 2c = 28
-c = 30
c = -30
b = -30 - 2
= -32
b = 4a
a = b/4
a = -32/4
a = -8
Therefore, the three numbers = -8, -32, -30
So what you do is evaluate g(2) then plug that value in for x in f(x)
g(2)=2^2-6(2)-7
g(2)=4-12-7
g(2)=-15
now
f(-15)=-15+8
f(-15)=-7
f(g(2)=-7
Hello from MrBillDoesMath!
Answer:
41 sqrt(3)
Discussion:
My first reaction to the problem was:
sqrt(27) = sqrt ( 3 * 9) = 3 sqrt(3) and
sqrt(48) = sqrt (3*16) = 4 sqrt(3).
So...
7 * sqrt(27) + 5 sqrt(48) =
7 * (3 sqrt(3)) + 5 * (4 sqrt(3)) =
21 sqrt(3) + 20 sqrt(3) =
41 sqrt(3)
