Answer:-
first take the angle sum property in triangle CAB
45+30+∠B=180
75+∠B=180
∠B=180-75
∠B=105
In a parallelogram, opposite angles are equal
therefore,
∠D=105(opposite angles are equal)

5√5 can be written in the form [tex]5^{k}[/tex]
Find the value of k
Answers
Answer:
n=3/2
Step-by-step explanation:
5 = 5^(1/2)
5√5 = [5^1] * [5^(1/2)]
when you multiply you add exponents
5√5 = 5^(1 + 1/2)
but 1 = 2/2
so
5√5 = 5^[(2/2) + (1/2)] = 5^[3/2]
Reed is currently r years old. Which expression represents his age seven years from now
Answers
Answer: r+7
Whatever his age is now, we add 7 to it. So we simply add 7 to r getting r+7.
Example: Say he is 10 years old now
r = 10
r+7 = 10+7 = 17
meaning he will be 17 seven years from now

Answer:
m∠5 = 67
m∠7 = 67
Step-by-step explanation:
m∠4 and m∠5 add up to 180 because they are same side interior angles.
180 - 113 = m∠5
m∠5 = 67
m∠5 = m∠7 because they are vertically opposite angles
hence, m∠7 = 67 degrees
Answer:
angle 5: 67 degrees. Angle 7: 67 degrees. (make sure to add the degrees logo)
Step-by-step explanation:
basically, angle 4 is 113 degrees. 180 degrees minus 113 is 67, which is how much angles 1 and 3 are. angles one and three are also equivalent to 5 and 7, which means they are also 67 degrees

3x^2-14=13
Answers
Answer:
x = ± 3
Step-by-step explanation:
Given
3x² - 14 = 13 ( add 14 to both sides )
3x² = 27 ( divide both sides by 3 )
x² = 9 ( take the square root of both sides )
x = ± [tex]\sqrt{9}[/tex] = ± 3

The describes a prediction for the end behavior of the graph of f(x) is
∞, f(x) - ∞ and x- (-∞), f(x) - ∞.
What is End Behavior of function?
The behaviour of the function graph at the "ends" of the x-axis is known as the end behaviour of a function, or f.
In other words, if we look at the right end of the x-axis (as x approaches + ∞) and the left end of the x-axis (as x approaches -∞), the end behavior of a function represents the trend of the graph.
We have,
the table as
x -5 -4 -3 -2 -1 0 1 2 3
f(x) 14 6 0 -4 -6 -6 -3 0 6
If we look at the table then we can conclude for further values
x tends to ∞ then f(x) tends to ∞
and, when x tends to -∞ then f(x) tends to ∞.

1. 3x^2 - 4x = 0
Answers
Step-by-step explanation:
By solving, I am assuming that you want to find the zeros.
So to find what x equals, first, you factor out an x.
3x² - 4x = 0
x(3x - 4) = 0
Here, you can separate the equation into two different equations to solve for x.
3x - 4 = 0 and x = 03x = 4x = [tex]\frac{4}{3}[/tex] and x = 0
Those are your zeros.
And for its graph, you can always look to an online graphing calculator. I used Desmos.

Answers
B well tip is 10% so do 15 times 10 + 15 and that will be your answer for b
Answer:
.99
18.99
Step-by-step explanation:
The answer to the first one is o.99 bc you would change 6.6% to a decimal and that would be 0.066 then you would add one to it and multiply it by 15 so the equation would look like this 1.066*15=0.99
The answer to the second one is 18.99 bc you would add 20% to 6.6% to get 26.6% and then you would change that into a decimal and add one to it to get 1.266 then multiply it by 15 to get 18.99

Point K is on line segment \overline{JL} JL . Given JK=5x+7,JK=5x+7, JL=2x+8,JL=2x+8, and KL=4,KL=4, determine the numerical length of \overline{JL}. JL .
Answers
Answer:
JL = 6 units
Step-by-step explanation:
It is given that,
K lies on line segment JL.
We have, JK=5x+7,JL=2x+8, and KL=4.
JL = JK + KL
2x+8 = 5x+7 + 4
Taking like terms together.
8-7-4=5x-2x
-3 = 3x
x = -1
Put x = -1 in JL = 2x+8. So,
JL = 2(-1)+8
JL = 6
Hence, the length of JL is 6 units.
