Answer:

$(9x-5)\ units$

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The perimeter of a triangle is the sum of the length of their three sides

$P=a+b+c$

where

a,b,c are the length sides of the triangle

In this problem we have

$P=(16x-6)\ units\\a=(2x-5)\ units\\b=(5x+4)\ units$

substitute and solve for the missing length

$(16x-6)=(2x-5)+(5x+4)+c\\c=(16x-6)-(2x-5)-(5x+4)\\c=(9x-5)\ units$

I REALLY NEED HELP!

Snowcat [4.5K]

Answer:

Step-by-step explanation:

The compound interest formula is $A = P (1+r/n)^nt$ where:

P is the starting amount called the principle
r is the rat written as a decimal
n is the number of times compounded in a year
t is the number of years

Substitute a value into each variable to solve.

P = $147 since 10% of 1,470 is being invested which makes P = 0.10(1470) = 147.

The rate is 3.5% or r = 0.035.
n = 12 because it is compounded monthly meaning 12 times a year.
t = 25 since it will earn for 25 years.

$A = P (1+r/n)^{nt}\\A = 147(1 + \frac{0.035}{12})^{12*25}\\A = 147 ( 1 + 0.002916)^{300}\\A = 147(1.002916)^{300}\\A = 352.19$

Repeat this process for each formula.
