Answer:
k(x) = -40
i(x) = -15
n(x) = 71
d(x) = 17
Step-by-step explanation:
This is exactly the same deal as the most recent question you asked.
"Evaluate each function for x = 8". In other words, this is saying, calculate the result for each function, replace x with 8. So, that means for every function, you are going to replace x with 8.
k(x) = -5x turns into k(x) = -5(8)
Then you just solve, -5(8) = -40
Since I have answered this question similarly, I ask that you go back to the answer and detailed explanation I gave you earlier.
Answer: I would say 135
Step-by-step explanation:
Answer:
55.5 square feet
Step-by-step explanation:
so the dog house consists of 4 walls, two roof sections, and two triangle bits to make the roof pointy (I'm sure they have a name but I don't know what it is lol) Of the walls there would be 2 of the longer walls and 2 of the shorther ones. Knowing this we just have to add together the area of each part to find the total surface area.
So starting with the walls:
two of them are 4 feet by 2 feet.
The area of a rectangle is just length x width
so those two would have an area of 8 ft^2
and the other two are 3 feet by 2 feet so they would have an area of 6 ft^2
the roof sections are also rectangles with dimensions of 4 feet by 2.5 feet
4x2.5=10 so each side of the roof has a surface area of 10 ft^2
now the triangle parts have a base of 3 feet and a height of 2.5 feet
the formula for area of a triangle is base x height / 2
3x2.5=7.5
7.5/2= 3.75
now we add them together
8+8+6+6+10+10+3.75+3.75=55.5
so the total surface area is 55.5 square ft
Answer:
RST
Step-by-step explanation:
Look at the angles for M, N and O. They are equal to 79, 60, and 42 degrees, respectively. Now look at the triangle to the right of triangle MNO. In what order should we line up the letters so that the angles for that triangle should also equal 79, 60 and 42 degrees? If you look at it for a second, you should that this problem is easy to solve! Did you get it right! That's right, by lining up the angles in the order RST, the measure of each angle is equal to the measures of MNO.
Give me Brainliest and have a great day! :)

70000- ten thousand
8000- thousand
000- hundred
00- tens
0- ones
so look at the 7 and if the number on the right is more than 4 you give the ten thousand a new number ; 80000
hope i helped
