Answer:
x^2 - y^2
Step-by-step explanation:
In the following problem, we can use the distributive property to simplify:
(x + y)(x - y)
We can start by multiplying the x's together, giving us x^2.
Next is the first x multiplied by -y in the second parenthesis. This gives us -xy.
Now, we can move on the the y in the first parenthesis: y times x(in the second parenthesis) is xy.
Lastly, we have y times -y which gives us -y^2.
(This process is shown in the image attached)
If we aa these together we get:
x^2 - xy + xy - y^2
If we add -xy and xy it would be 0 because if you add a number with it's opposite, they cancel out. We are just left with x^2 - y^2.

A car has a speed of 25 m/s. What is its speed in km/hr? (1 km = 1000 m) (1
hr = 3600 s)
Answers
Step-by-step explanation:
the car went 25 meters in 1 second.
that creates this ratio 25 m/s or
formally fully correct 25/1 m/s.
to get the speed in km/h we need to bring the denominator of that ratio from 1 second to 1 hour.
we do that by multiplying it by 3600, as there are 3600 second in 1 hour.
to keep the overall value of the ratio we need to multiply also the numerator with the same factor.
so,
25/1 × 3600/3600 = (25×3600)/3600 =
= 90000 meters /1 hour
how many km (kilometers) are 90000 meters ?
1 km = 1000 m
so,
90000 m = 90000/1000 km = 90 km
therefore, or full answer is
the car's speed was 90 km/h.
The vertices of quadrilateral MNPQ are M(−3,−2),N(−1,4),P(2,4), and Q(4,−2). Translate quadrilateral MNPQ using the vector ⟨3,−4⟩.
The vertices of M′N′P′Q′ after the translation are?
Answers
Answer:
see explanation
Step-by-step explanation:
A translation using the vector < 3, - 4 > , means
Add 3 to the x- coordinate and subtract 4 from the y- coordinate, so
M (- 3, - 2 ) → M' (- 3 + 3, - 2 - 4 ) → M' (0, - 6 )
N (- 1, 4 ) → N' (- 1 + 3, 4 - 4 ) → N' (2, 0 )
P (2, 4 ) → P' (2 + 3, 4 - 4 ) → P' (5, 0 )
Q (4, - 2 ) → Q' (4 + 3, - 2 - 4 ) → (7, - 6 )

Angle TVZ makes a linear pair with angle ZVW so the measure of angle TVZ plus the measure of angle ZVW=180 degrees. Angle ZVW is also a linear pair with angle RVW. Angle RVW is a vertical angle to angle TVZ. Use these relationships to determine the measure of angle TVZ.

eats 54 nathan's hot dogs in 12 minutes. number of hot dog per minute rate of change
Answers
Answer:
4.5 hot dogs per minute
Step-by-step explanation:
rate of change=hot dog/minutes=54/12=4.5
Answer:
4.5 Hotdogs per Minute
Step-by-step explanation:
Rate of change is found by dividing the total amount of an object, in this case the hotdogs, by the amount of time.
We know that Nathan has 54 hotdogs and that he eats them in 12 minutes.
Therefore: [tex]\frac{54}{12}[/tex] is the rate of change.
This can be simplified to 4.5 as the rate of change.

Notice that only the first and third monomials (when simplified) contain the exact same variables with the same exponents. Therefore, those are the only two monomials we can add together.
(10/6 - 7/6)(a^4)(b)(c)(x^3) - 2.07(a^4)(b)(x^3)

Since this expression has two terms, it is a binomial.

Find the unknown sizes of angles with step by step explanation please:
Answers
Step-by-step explanation:
y= 80 because alternate angles are equal
80+57=137
180-137= 43 because angles in a triangle add up to equal to 180
z= 43
180-80= 100
the angle P is 90 so 100+80+90=270
360-270=90 as the sum of the angles in a quadrilateral its 360
so
x= 90
y= 80
z= 43

(a) Write the point–slope form of a function that has a slope of -3 and passes through the point (11, 2).
(b) Using the point–slope form of the function found in part a, compute the y-intercept of that function by setting x =0 and solving for y.
(c) Write the slope–intercept form of the function found in part a
Answers
a. Point-slope form is: y - y0 = m(x - x0). Plugging in our values, we get: y - 2 = -3(x - 11). Typically we can just leave it like this, but for the sake of simplifying it down to slope-intercept form, it would be y = -3x + 35.
b. y - 2 = -3((0) - 11)
y - 2 = 33
y = 35.
c. y = -3x + 35.

if the sum of interior angles of a polygon is 30 right angles how many sides does the polygon
Answers
Answer:
17 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 30 × 90° = 2700° , then
180° (n - 2) = 2700° ( divide both sides by 180° )
n - 2 = 15 ( add 2 to both sides )
n = 17
Answer:
17 sides
Step-by-step explanation:
-Let the number of sides of the polygon be n
The sum of the interior angles of a polygon of n sides is.180° (n−2)
The sum of interior angles =30×90°
30×90° =180°(n−2)
15=n−2
n=17
