Answer:
f(f(x)) = x⁴ + 2x² + 2
Step-by-step explanation:
if f(x) = x² + 1, then f(f(x)) is equal to:
f(x)² + 1
= (x² + 1)² + 1
= x⁴ + 2x² + 1 + 1
= x⁴ + 2x² + 2
Answer:
156ft of material.
Step-by-step explanation:
Since the garden path borders the garden and is 3 feet wide, it increases the side lengths of his garden by 3 feet on each side. Then we just find the perimeter using the new values:

The value of x is less than or equal to 2.25.
<h2>Linear system</h2>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
<h3>Simplification</h3>
Simplification is to make something easier to do or understand and to make something less complicated.
Given
The expression is 47.75 + x ≤ 50.
<h3>To find</h3>
The value of x.
<h3>How to find the value of x?</h3>
The expression is 47.75 + x ≤ 50.
On simplifying,
47.75 + x ≤ 50
x ≤ 50 - 47.75
x ≤ 2.25
Thus, the value of x is less than or equal to 2.25.

Step-by-step explanation:
the inner top vertex angle seems to be 90°, so x = 90° too. all angles around a single point in one side of a line are in total 180°.
also, remember, all angles inside a triangle always sum up to 180°.
so, the third inner angle of the triangle is
180 - 90 - 40 = 50°.
that makes z = 180 - 50 = 130°
and y = 180 - 40 = 140°.
8x8x8x8x8 is the answer. The 5 as the exponent means that you are multiplying 8 by itself 5 times.
