2x - 19
Step-by-step explanation:
Perimeter = sum of sides
First let's simplify each side
We can simplify each side by using distributive property. Distributive property is where you multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.
2(x + 5)
Distribute by multiplying x and 5 by 2
2 * x = 2x and 2 * 5 = 10
2x + 10
1/2(4x + 8)
Distribute by multiplying 4x and 8 by 1/2
1/2 * 4x = 2x and 1/2 * 8 = 4
2x + 4
-3(2x + 11)
Distribute by multiplying 2x and 11 by -3
-3 * 2x = -6x
-3 * -33
-6x - 33
Finally add all the simplified expressions ( remember that they represent the side lengths of the triangle )
2x + 10 + 2x + 4 - 6x - 33
Combine like terms
2x + 2x - 6x = -2x
10 + 4 - 33 = -19
Perimeter: -2x - 19

8 + (-5)
Answer: 3
Step-by-step explanation: 8 + (-5) is the same as saying 8 - 5 and 8-5 = 3
8 + (-5)
A negative and a positive make a negative therefore 8 + (-5) changes to
8 - 5
8 - 5 = 3

Help please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
2(x+7)=72 no, because this only changes the value on the right side. so this equation is not about the same equality anymore.
x+7=18 yes, because both sides were transformed by the same operation (division by 2). the equality is still maintained.
2x+7=36 no, because 2x+7 is NOT equal to 2(x+7). resolving 2(x+7) is 2x+14.
x+14=36 no, because again, x+14 is NOT equal to 2(x+7).
(2×x) + (2×7) = 36 yes, because the left side is a valid transformation of 2(x+7).
2x+14=36 yes, because the left side is a valid transformation of 2(x+7).
If you know two angle measures of a triangle in spherical geometry, can you always find the measure of the third angle? Explain.
A. Yes; the angle measures of a triangle always sum to 180.
B. Yes; the angle measures of a triangle always sum to 270 in spherical
geometry.
C. No; the sum of angle measures in spherical geometry is always greater than
180, but there is not a particular number they must sum to.
D. No; the sum of angle measures in spherical geometry is always greater than
270, but there is not a particular number they must sum to.
When two angle measure of a triangle are given in spherical geometry: The sum of angle measures in spherical geometry is always greater than 180, but there is not a particular number they must sum to. Choice C (No) is correct
According to the question;
Two angle measures of a triangle in spherical geometry are given.However, unlike in plane geometry where affirmatively, the sum of angles in a triangle is equal to 180°.
In spherical geometry;
The totality of the angles of a triangle on a sphere is given as 180°(1 + 4x), where x is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of x, which in each case exceeds 180°.

6900 dollars is placed in account with an annual interest rate of 8.25%. How much will be in the account after 26 years, to the nearest cent.
Answer:
$54196.92
Step-by-step explanation:
6900x1.0825^26
1.0825 is the multiplier
The correct answer is $54196.92.
Step by step =
6900x1.0825^26 = 54196.92.
How do you calculate the annual interest rate?
The formula and calculations are as follows:
Effective annual interest rate = (1 + (nominal rate / number of compounding periods)) ^ (number of compounding periods) - 1.For investment A, this would be: 10.47% = (1 + (10% / 12)) ^ 12 - 1.And for investment B, it would be: 10.36% = (1 + (10.1% / 2)) ^ 2 - 1.Is the interest rate annual or monthly?
The interest rate is the amount a lender charges a borrower and is a percentage of the principal of the amount loaned. The interest rate on a loan is typically noted on an annual basis known as the annual percentage rate (APR).

Subtract 2w from both sides.
2l=48−2w
Divide both sides by 2.

2l
=

48−2w
Dividing by 2 undoes the multiplication by 2.
l=
2
48−2w
Divide 48−2w by 2.
l=24−w
Answer:
14centimeters
Step-by-step explanation:
from our equation,
2l + 2w = 48
we know that the width = 10cm
so,
2l + 2( 10 ) = 48
2l + 20 = 48
2l = 48 - 20
2l = 28
divide through by 2
2l / 2 = 28 / 2
l = 14
therefore,
l = 14 centimeters
