Answer:
([tex]\sqrt{7}[/tex] - x )([tex]\sqrt{7}[/tex] + x )
Step-by-step explanation:
Using the difference of squares
a² - b² = (a - b)(a + b) , then
7 - x²
= ([tex]\sqrt{7}[/tex] )² - x²
= ([tex]\sqrt{7}[/tex] - x)([tex]\sqrt{7}[/tex] + x)

An angle measures 52.8 degrees more than the measure of its supplementary angle. what is the measure of each angle?
Answer: 116.4 and 63.6 degrees
Step-by-step explanation:
Let the angle be x, so supplement is 180-x.
This means x - 52.8 = 180 - x
2x = 232.8
x = 116.4
So the angle measures are 116.4 and 63.6 degrees

1) How do you find the sum of the exterior angle measures of any convex polygon?
2) If the polygon is regular, how do you find the measure of each exterior angle in the polygon?
Answer:
1) sum of all convex polygons' EXTERIOR ANGLES IS ALWAYS 360 DEGREES. If it is a triangle or even if it is a 25- gon.
2) if the polygon is regular then this means all of the sides are equal and all of the angles are equal to each other.
for example: Find the measure of an exterior angle of a REGULAR HEXAGON. so a regular hexagon has 6 sides all the same length and 6 exterior angles all the same measures. so to find the measure of 1 exterior angle you do 360 degrees /6 = 60 degrees. so an exterior angle of a regular hexagon is 60 degrees.
DeShawn is 38 years old and is married with 3 children, ages 2, 4, and 6. He makes $45,000 a year and is planning to retire when he turns 60.

If 6 men can dig 4 ditches in an hour.how many men would be required to dig 6 ditches

Step-by-step explanation:
Let f(x)=−2x+3f(x)=-2x+3. Find each of the following:
f(a)=f(a)=
2f(a)=2f(a)=
f(2a)=f(2a)=
f(a+2)=f(a+2)=
f(a)+f(2)=f(a)+f(2)=
Answer:
1. f(a) = -2a + 3
2. 2f(a) = -4a + 6
3. f(2a) = -4a + 3
4. f(a+2) = -2a - 1
5. f(a) + f(2) = -2a + 2
Step-by-step explanation:
for each one, just plug whatever is inside the parentheses inside the equation as x. For example, f(a) = -2(a) + 3. The a replaces all the x's

Answer:
3.9
Step-by-step explanation:
Let's do this. Sally can paint 1/7 of the room in an hour while Steve can paint 1/9 of the room in an hour. 1/7+1/9 = 16/63. Two of them working together can paint 16/63 of a room in an hour. Now, let's divide 63 by 16.
Use a calculator from here.
63/16 = 3.9375
3.9375 rounded to one decimal place would be 3.9 and not 4, since the next number after 9, which is 3, is not up to 5. If it were 5 to 9, then the answer would be 4.

Which figure shows the correct dimensions of a 310 scale drawing of the given figure?
Answer: the scale copy of the given figure is the fourth answer
Step-by-step explanation:
Ray hired a moving company to help him move to a new apartment. The equation below.
represents the relationship between the number of hours it takes to move (x) and the total cost
to move (y).
- 100 = 240x - 2y
What is the cost per hour?
Answer:
$120/hr
Step-by-step explanation:
if x is hours to move and y is total cost, let's rearrange the equation so that it is easier to understand. I'd say isolate y (total cost) and see what it is equal to:
- 100 = 240x - 2y
2y = 240x + 100
y = 120x + 100
What I see is: Total Cost = 240*(Hours to move) + 100
That tells us that each hour is $120. It also discloses that there appears to be an upfront charge of $100, before any work is done( even at 0 hours). [If the movers come to the apartment, but you've changed your mind, then it still costs $100].
It also tells us that the charge per hour is $120. [If I had a pickup, I'd do it for $100/hour, but my tiny Honda Accord trunk barely holds the spare tire.]

more than 3 times the amount Cara has saved. How
much money has each girl saved?
Let the amount Cara has is X
Amber has 3x +3
Together they have 43:
3x +3 + x = 43
Simplify:
4x +3 = 43Subtract 3 from both sides:
4x = 40
Divide both sides by 4:
x = 10
Cara has $10 and Amber has $33
Answer:
Cara saved $43 and Amber saved $132.
Step-by-step explanation: 3+3(43)=132
