Henry drew a rectangle with a length 5 times as long as its width. Which expression can be used to find the perimeter of the rectangle?a. 5w + w
b. 5w + 5w
c. 2(5w + w)
d. 2(5w + 5w)

Answers

Answer 1

Answer: Hello,

w= the width
5w the length
2*(5w+w) is the perimeter (or 12w)
Answer C

**WILL GIVE BRAINLIEST**Example 2: Leonardo saw the new sound system he wanted for $2623.95, including taxes. He had to buy it oncredit and had two options:-Use his new bank credit card, which has an interest rate of 14.5% compounding daily (Because the thiscredit card is new, he has no outstanding balance from the previous month)Apply for the store credit card, which offers an immediate rebate of $100 on the price, but has an interestrate of 19.3%, compounded daily.As with most credit cards, Leonardo would not pay any interest if he paid off the balance before the due date onhis first statement. However, he cannot afford to do this. Both cards require a minimum monthly payment of 2.1%on the outstanding balance, but Leonardo is confident that he can make regular payments of $110.

How to i find the missing 2 angles

Answers

Answer:

therefore, x is 71 degrees

Step-by-step explanation:

we know that the exterior angle is 142 degrees.

we also know that we have to find x, which is labeled two times as an interior triangle (in the same triangle), so they must be the same degree.

there are different ways to solve this but the easiest way is this:

exterior angle = opposite interior angle 1 + opposite interior angle 2

142 degrees = x + x

142 degrees = 2x

142/2 = x

x = 71

therefore, x is 71 degrees

Fill on the other coordinate for the line 2x-3y=4 (2,)

Answers

For the first coordinate they have given it to you, so plug it in to get the y coordinate.
2x -3y = 4
2 * 2 - 3y = 4
4 - 3y = 4
4 - 4 - 3y = 4 - 4
-3y = 0
-3y/-3 = 0/-3
y = 0
(2, 0)
To find another set of coordinate to form a line, all you have to do is put in an x value that would make the line true.
2x -3y =4
2 * 8 - 3y = 4
16 - 3y = 4
16 - 16 -3y = 4 - 16
-3y = -12
-3y/-3 = -12/-3
y = 4

for this question we have:
(2, y)
and we know:
2x -3y = 4
so the only thing u need is to put 2 for x and find y:
2(2) - 3y = 4
4 - 3y = 4
-3y = 0
y =0 :)))
