Answer:
perimeter = 26
Step-by-step explanation:
<u>perimeter of a rectangle = 2L + 2W</u>
where:
L = 5x² - 2
W = 7 + 3x
Let x = 1
find: Perimeter
-----------------------------------------------
substitute values into the formula:
P = 2(5 * 1² - 2) + 2(7 + 3 * 1)
P = 2(3) + 2(10)
P = 6 + 20
P = 26
therefore,
the perimeter = 26
21. <DBE and <ABE are both equal halves of <ABD, so in this case, m<ABE = m<DBE, so all you have to do is solve the equation:
6x + 2 = 8x - 14
add 14 to both sides, subtract 6x from both sides.
16 = 2x
Divide both sides by two. The solution is x = 8. To find m<ABE, replace x with 2, so your final answer is 14. m<ABE = 14
22. From what we know from 21, m<ABE = m<EBD, so keep that in mind. We still have to solve for m<EBD. Since one line is 180 degrees, we are able to write out this equation using the information given:
180 = 9x - 1 (m<ABE) + 9x - 1 (m<EBD) + 24x + 14 (m<DBC)
simplify this:
180 = 12 + 42x
subtract 12 from both sides, then divide by 42.
4 = x
Now we plug this in.
4 × 9 = 36. 36 - 1 = 35.
m<EBD = 35
23. From the past two equations, we know m<ABE consistently equals m<EBD. This means that, if they are bisectors of a right angle, they both equal 45 degrees. here is our equation:
45 = 13x - 7.
we add seven to both sides and divide by 13.
4 = x
Hello Budnot8, I am here to answer your question:
So, to solve this problem, we just need to use a quick rule of 3, like this:
60*29 = 1740, then 1740/100 = 17.4, and that gives us our answer.
So the answer is: The 60% of 29 is 17.4
Hope this helped answer your question.
Answer:
Step-by-step explanation:
The radius of circle D is the distance from the origin to (-4, -7).
In math, the distance formula gives us the distance between two points, (x₁, y₁) and x₂, y₂):
You are really using Pythagoras' Theorem to find the distance. You are building a right triangle whose hypotenuse connects two given points.
For example, in the blue triangle below, the distance between the points (0,0) and (-4, -7) is
