Answer:
sqrt(29)
Step-by-step explanation:
We can find MN using the Pythagorean theorem
The height is 2 and the length is 5
a^2 + b^2 = c^2
2^2 + 5^2 = MN ^2
4 + 25 = MN^2
29 = MN ^2
taking the square root of each side
sqrt(29) = MN

Given the coordinates of point T at (-5,6) and point X at (3,2). What is the
coordinate for the midpoint of line segment TX?
Answer:
The midpoint is
( - 1 , 4 )Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
T( - 5 , 6) and X ( 3 , 2)
The midpoint is
[tex]M = ( \frac{ - 5 + 3}{2} \: , \: \frac{6 + 2}{2} ) \\ = ( - \frac{2}{2} \: , \: \frac{8}{2} )[/tex]

Ivan read a total of 15 books over 5 months. After belonging to the book club for 8 months, how many books will Ivan have read in all? Solve using unit rates.
Answer:
24 books.
Step-by-step explanation:
Because 15 books divide 5 months would be 3 books so each month is 3 books so 3 books times 3 more months would be 9 books and then you add 15 to 9 and you get 24.

(-8)(-5) I really need help
Answer: 40
Step-by-step explanation:
For this problem, you need to know the properties of multiplying negative numbers.
- × - = + [negative×negative=positive]
- × + = - [negative×positive=negative]
+ × - = - [positive×negative=negative]
+ × + = + [positive×positive=positive]
Now that we have established the different sign changes, we can multiply -8 and -5. Multiplying -8 and -5 would be the first option. We know that our answer would be positive.
(-8)(-5)=40

raise 2 to the 4th power, then add r to the result
Answer:
2⁴ + r
Step-by-step explanation:
Change the sentence into a expression.
Note that r is a variables.
"Raise 2 to the 4th power..." means 2 to the 4th power, or 2⁴.
"...then add r to the result" means: + r
Combine the two terms:
2⁴ + r is your answer.
~
Simplify if need be.
2⁴ = 2 * 2 * 2 * 2 = 4 * 4 = 16
r + 16 is your answer.

When you have two shapes to compare on a coordinate
plane, you can determine the scale factor, knowing that
the transformation was a dilation. Generate instructions
you would give another student to determine the scale
factor.
Locate two corresponding ordered pairs of the two shapes. Calculate how much the pre-image values were multiplied by to obtain the image values. This is your scale factor. You can calculate this by dividing the coordinates of the mage by the corresponding coordinates of the pre-image.
Answer:
First you have to find the ordered pairs for the shapes. Then figure out how much the pre-image was multiplied by. The number it was multiplied by is your scale value.

show that (-2, 1), (2, -2) and (5,- 2) are the vertics of the right triangle
Step-by-step explanation:
A= (-2,1)
B= (2,-2)
C=(5,2)
slope = y1 - y2/ x1- x2
slope of
AB = -2-1/2-(-2)
= -3/4
BC= 2-(-2)/5-2
= 4/3
AC = -2-1/5-2
= -3/3
=-1
if ABC is a right triangle then AB should be perpendicular to BC
AB x BC = -1
LHS
=-3/4 x 4/3
=-1
= RHS
hence triangle ABC is a right triangle

The value of m = 5
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A = 2 (2m) + 4 (4m + 2) = 108
Now , on simplifying the equation , we get
2 (2m) + 4 (4m + 2) = 108
4m + 4 ( 4m ) + 4 ( 2 ) = 108
4m + 16m + 8 = 108
20m + 8 = 108
Subtracting 8 on both sides of the equation , we get
20m = 100
Divide by 20 on both sides of the equation , we get
m = 5
Therefore , the value of m is 5
Hence ,
The value of m from the equation 2 (2m) + 4 (4m + 2) = 108 is m = 5

Mike had 228 dollars to spend on 7 books. After
buying them he had 18 dollars. How much did each book cost ?
Answer:
$30
Step-by-step explanation:
We know that the cost of all of the books was 228 - 18 = 210 dollars because Mike had 18 dollars left over. Assuming that each book cost the same amount, we know that each book costs 210 / 7 = $30.
Answer:
$30
Step-by-step explanation:
Total amount Mike had = $228
Amount remaining = $ 18
Amount spent on books = 228 - 18 = $210
Cost of wach book = 210/7 = $30
Cost of each book is 30 dollars.
