Answer: Determine whether (–x)3 + 5(–x) + 1 is equivalent to x3 + 5x + 1.

To determine if a function is even, we need to check if f(-x)=f(x).

I need help with #11 - #14.

Aleonysh [2.5K]

Answer:

I can get you jump started a bit.

Step-by-step explanation:

So Each of those pairs of figures are Similar.

This means they have equal angle measures but different side lengths.

To find it, we have to make a Proportion:

Example: #11

$\frac{x+1}{3x+1} =\frac{8}{20}$

So let's solve the first one!

$24x+8=20x+20\\4x=12\\x=3$

Easy As Pie!

If you need more help, contact me! :)

Hope this Helps!

A trapezoid has a height of 3 meters, a base length of 8 meters, and an area of 30 square meters. What is the length of the base

algol [13]

Answer:

Length of the second base will be 12 meters.

Step-by-step explanation:

Area of a trapezoid is given by the formula,

Area = $\frac{1}{2}(b_1+b_2)h$

Here, b₁ and b₂ are the bases of the trapezoid and 'h' is the vertical distance between the bases.

By substituting the values in the formula,

$30=\frac{1}{2}(8+b_2)3$

$60=3(8+b_2)$

$20=8+b_2$

$b_2=12$

Therefore, length of the second base will be 12 meters.
