Find the value of X

Mathematics
1 answer:
Morgarella [4.7K]3 years ago
8 0

Answer:

x = 7

Step-by-step explanation:

<> sum of the interior angles of the polygon is (8-2)*180 = 1080°

<> since all the lengths are equal it implies all the angles are equal

<> there are 8 angles

=> 8(16x + 23) = 1080

=> 16x + 23 = 135

=> 16x = 135 - 23

=> 16x = 112

=> x = 112/16

=> x = 7

The Todd family plans to start a small business. Mr. Todd borrows $10,000 from the blank at an annual interest rate 8%for 36 mon
Ede4ka [16]

Answer: They will end up paying $2,400.

Step-by-step explanation:

Since the annual interest rate is 8% of $10,000, take 8% of 10,000 by multiplying these numbers. This gives you $800.

This is only the annual interest rate, the Todd family's loan and interest isn't paid until 36 months have passed. Since 36 months is equal to 3 years, we can multiply the annual rate by 3. (800*3)

The Todd family will pay $2,400 in interest by the end of the period.

Simplify
guapka [62]
The first is a. you can rewrite it
\sqrt{x^5} = \sqrt{x^2x^2x} = \sqrt{x^2}\sqrt{x^2}\sqrt{x} = xx\sqrt{x} = x^2\sqrt{x}

the second is d. the only common factor between 20 and 40 that can be taken out is the 4 which becomes a 2, but inside the square roots there is still a 5 and 10, which cannot be combined

the third is c.
\sqrt{36x} + \sqrt{100x} - \sqrt{25x} \\ 6\sqrt{x}+10\sqrt{x}-5\sqrt{x} \\ 11\sqrt{x}

the fourth is d.
add 3 to both sides \sqrt{2x} = 10
then square both sides 2x=100
then divide both sides by 2, x=50
