Answer:
Step-by-step explanation:
The perimeter of a rectangle is
P=2(L+W)
We are given L=3x+9 and W=2x-5 so
P=2(3x+9+2x-5)
P=2(5x+4)
P=10x+8

Click an item in the list or group of pictures at the bottom of the problem and, holding the button down, drag it into the correct position in the answer box. Release your mouse button when the item is place. If you change your mind, drag the item to the trashcan. Click the trashcan to clear all your answers. Factor completely and then place the factors in the proper location on the grid. 25a 2 - 30a + 9
Answer:
(5a−3)^2
Step-by-step explanation:
25a^2 - 30a + 9
Factor the expression by grouping. First, the expression needs to be rewritten as 25a^2+pa+qa+9. To find p and q, set up a system to be solved.
p+q=−30
pq=25×9=225
Since pq is positive, p and q have the same sign. Since p+q is negative, p and q are both negative. List all such integer pairs that give product 225.
−1,−225
−3,−75
−5,−45
−9,−25
−15,−15
Calculate the sum for each pair.
−1−225=−226
−3−75=−78
−5−45=−50
−9−25=−34
−15−15=−30
The solution is the pair that gives sum −30.
p=−15
q=−15
Rewrite 25a^2 - 30a + 9 as (25a^2−15a)+(−15a+9).
(25a^2−15a)+(−15a+9)
Factor out 5a in the first and −3 in the second group.
5a(5a−3)−3(5a−3)
Factor out common term 5a−3 by using distributive property.
(5a−3)(5a−3)
Rewrite as a binomial square.
(5a−3)^2

Which statement describes the graph of f(x)=Lx]-2 on [0, 3)?
The steps are at y = -2 for 0 5x < 1, at y=-1 for 1 Sx < 2, and at y = 0 for 2
O The steps are at y = 0 for I Sx <1, at y = 1 for 1
O The steps are at y = 1 for 0
O The steps are at y = -3 for i Sx <1, at y=-2 for 1 Sx <2, and at y = -1 for 2
f(x) = -Lxl is the function and -3 ≤x≤3 is the domain that could represent the given graph .
What is a function ?Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
here, we have,
We know, domain is:
The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
Thus , from the graph it can be clearly depicted that it is representing f(x)=-Lxl for an entire range of -3 ≤x≤3 .
Hence , f(x) = -Lxl is the function and -3 ≤x≤3 is the domain that could represent the given graph .

(4y+7)
(3y+5)
Answer:
24
Step-by-step explanation:
(4y + 7) + (3y + 5) = 180. (angle on a straight line =180)
4y + 7 + 3y + 5 =180
4y + 3y + 7 + 5 = 180
7y + 12 = 180
7y = 180 - 12
7y = 168
y = 168/7
y = 24

Unit 10: Circles Homework 4: Inscribed Angles
Find each angle or arc measure of mRS
Answer:
96 degrees
Step-by-step explanation:
Since you know that arc are twice the angle measure, that means arc RT is 42 * 2 = 84. Then, you have to find the measure of RS.
Remember that arc RT and RS have to add up to 180 degrees because they form a semicircle (half of a circle).
To find the measure of RS, just do 180 - 84 = 96 degrees.

Leon older brother is 4 and 3/4 feet tall Leon is 1/3 foot shorter than his brother how tall is Leon
Answer:
4 5/12 feet tall
Step-by-step explanation:
All you have to do is subtract 1/3 from 4 and 3/4 in order to get this answer.
Answer:
Leon is 53/12 feet or 4 & 5/12 or 4.4167 (same answer different forms)
Step-by-step explanation:
Leon older brother is 19/4 feet tall or 57/12.
Leon is 1/3 or 4/12 foot shorter than his brother.
57/12-4/12= 53/12

Solve these and the conclusion is that it needs to be greater than 3 but less than 17.
Answer:
D) greater than 3 but less than 17
Step-by-step explanation:
The third side must be greater than the difference and smaller than the sum of the two other sides.
10-7=3
10+7=17
so the third side must be greater than 3 and less than 17

what is the slope line
Answer:
In technical terms, the slope of the line is the change in y over the change in x. But I just like to think of it as rise over run. To find the slope of the line, pick two points on the line.
Answer:
Uphill slopes are positive slopes.
The slope will be a positive number like 5 or 2/3.
Downhill slopes are negative slopes.
The slope will be a negative number like -7 or -1/3.
