If a certain number equals the same number, then all numbers will work.
For example: if 4=4, then all numbers would work.

The perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used

Lady_Fox [76]

Perimeter is the sum of all sides of a polygon. For this case, the perimeter is expressed as: P=a+b+c. It has been said that the longest side is twice that of the shortest side. Let's assume that a is the longest side and b is the shortest side. So, the equation for the shortest side is,

6.2 = 2c
c = 3.1

14.5 = 6.2 + 3.1 + b
<span>14.5 = 9.3 +b</span>

Find the product of (x − 5)2. (1 point) Group of answer choices x2 + 10x + 25 x2 − 10x + 25 x2 − 25 x2 + 25

Anuta_ua [19.1K]

Answer:

$x^2 - 10x + 25$

Step-by-step explanation:

Hello!

Expand the square using the Distributive Property.

<h3>Expand</h3>

$(x - 5)^2$
$(x - 5)(x-5)$

Distributive x - 5 to each factor

$x(x - 5) -5 (x - 5)$
$x^2 - 5x - 5x+25$
$x^2 - 10x + 25$

The answer is $x^2 - 10x + 25$ .

We can also use a special binomial product formula.

Formula: $(a - b)^2 = a^2 - 2ab + b^2$

$(x - 5)^2 = x^2 - 2(x)(5) + 5^2$
$(x - 5)^2 = x^2 - 10x + 25$

We get the same answer both ways.

What is the zero for 2x2-7=4

rosijanka [135]

2x^2-7=4
subtract 4 from both sdies
2x^2-11=0
therefor
2x^2=11
divide by 2
x^2=5.5
square root both sdies
x=-2.345 or 2.345

You start your working career when you are 24 years old. Each month, you deposit $144 into a pension plan. You continue making d

Inga [223]

The balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is <u>$372,134.19</u>.

<h3>What is future value?</h3>

The future value refers to the compounded future value of an asset, for example, a pension plan, based on a growth rate of interest for a future period.

The future value can be determined with the FV formula, table, or using an online finance calculator as follows:

<h3>Data and Calculations:</h3>

N (# of periods) = 528 months (68 - 24 x 12 months)

I/Y (Interest per year) = 6%

PV (Present Value) = $0

PMT (Periodic Payment) = $144

<u>Results:</u>

FV = $372,134.19

Sum of all periodic payments = $76,032 ($144 x 528)

Total Interest = $296,102.19

Thus, the balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is <u>$372,134.19</u>.
