Answer:
36
Step-by-step explanation:
Here, f(x) is the input to g(x), forming a composite function.
To evaluate (gºf)(5),
1) find the value of f(5). It is f(5) = 6.
2) Use this result as the input to g(x): g(6) = (6)^2 = 36
Answer:
x=9
Step-by-step explanation:
Step 1: Simplify by both sides of the equation.
80-3x=53
80+-3x=53
-3x+80=53
Step 2: Subtract 80 from both sides.
-3x+80-80=53-80
-3x=-27
Step 3: Divide by both sides by 3.
-3x/-3 = -27/-3
x=9
Answer:
20
Step-by-step explanation:
straight line is 180 degrees
110+?=180
?=70
y=90 because it is a right angle
All angles of a right triangle added equals 180
so 70+90=160
180-160=20
x=20
Answer:
<h2>The answer is 8 ft</h2>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
perimeter = 40 ft
length = 12 ft
Substitute the values into the above formula and solve for the width
That's
40 = 2(12) + 2w
40 = 24 + 2w
2w = 40 - 24
2w = 16
Divide both sides by 2
We have the final answer as
<h3>8 ft</h3>
