i need help on this (-4)²
help me
Answer:
Step-by-step explanation:
To have anything to a power is just multiplying the number as many times as it says to. ex. 2^3 is two times itself 3 times. 2 x 2 x 2= 8
In your case, you need to multiply -4 x -4 because the exponents tell you how many of the number you multiply.
-4 x -4 = 16
Hope this helps :)

Find the product of 2r^2(6r^3+14r^2-30r+14)
Answer:
12 [tex]r^{5}[/tex] + 28 [tex]r^{4}[/tex] - 60 r³ + 28 r²
Step-by-step explanation:
a(b ± c) = ab ± ac (distributive property)
[tex]a^{m} * a^{n} = a^{m+n}[/tex]
2r²(6r³ + 14r² - 30r + 14) = 12 [tex]r^{5}[/tex] + 28 [tex]r^{4}[/tex] - 60 r³ + 28 r²
Answer: 2r2(6r3+14r2−30r+14)
Step-by-step explanation:
Apply the distributive property
2r2(6r3)+2r2(14r2)+2r2(−30r)+2r2⋅14
Simplify
2⋅6(r2r3)+2⋅14(r2r2)+2⋅−30(r2r)+28r2
Simplify each term
12r5+28r4−60r3+28r2
Mary left the place called Apton and rode towards the place Brandon at the same speed for 2 hours. She reached the sign shown below. Mary continues to ride at the same speed towards Brandon. How many hours will it take for her to ride from the sign to Brandon?
Answer:
Time taken by Mary to get to Brandon = 3 hours
Note: The complete question is found in the attachment below
Step-by-step explanation:
Step 1: Determining the average speed of Mary
At the sign, it shows that Mary has travelled 30 km from Apton in 2 hours to get to the sign.
Therefore, the average speed of Mary is given by;
average speed = total distance/time taken
average speed = 30 km/ 2 hours = 15 km/hr
Step 2: determining the time taken to get to Brandon
Also, from the sign, it can be seen that Brandon is still 45 km ahead. Since Mary continues at the same speed, the time taken will be;
time taken = total distance/average speed
time taken = 45 km/ 15 km/hr
time taken = 3 hours

r + 8 - 5r = 2(4 - 2r) solve for r please
-4r + 8 = 8 - 4r
0 = 0 so it's like {}
Answer:
r = 0
Step-by-step explanation:
This is actually the first time I've actually had a equation with the variable equaling 0.
so first things first you have the equation:
r + 8 - 5r = 2(4 - 2r)
so you are going to add or multiply all the variable numbers together and the none variable numbers together like so:
r + (-5r) and (2*4) and (2* (-2r)) to get the equation looking like so:
8+ (-4r)= 8 -4r
you then add -4r to both sides to get this equation:
8+ ( -4r)= 8 -4r
+ 4r +4r
8 = 8 + r
you then subtract 8 from both sides to get r:
8 = 8 + r
-8 -8
0 = r
to check substitute the 0 into r in the equation:
r + 8 - 5r = 2(4 - 2r)
0 + 8 - (5*0) = 2(4- (2*0))
8 = 8
Tada!!!

Here are two rectangles.
B
A
The length of rectangle B is 25% greater than the length of rectangle A.
3
The width of rectangle B is three fifths x the width of rectangle A.
Find the fraction of area of rectangle b over area of rectangle a
Give your answer in its simplest form.
Answer:
[tex] \frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}[/tex]
Step-by-step explanation:
Let the length of rectangle A be x units.
So, length of rectangle B
= x + 25% of x
= x + 0.25x
= 1.25x
Let the width of rectangle A be y units
So, Width of rectangle B
[tex]= \frac{3}{5}\times x\\
=0.6x [/tex]
Area of rectangle A = xy
Area of rectangle B
= 1.25x * 0.6y
= 0.75xy
[tex] \frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{xy}{0.75xy}\\\\
\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{1}{0.75}\\\\
\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{100}{75}\\\\
\red{\bold{\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}}} \\\\[/tex]
What division problem can be represented using the number line?

A $20.00 pair of jeans is discounted 20%. What is the final price of the jeans?
Answer:
It should be 4 dollars I believe
Step-by-step explanation:
Answer:
It is given that a $20.00 pair of jeans is discounted 20%. We need to find the final price of the jeans. Therefore, the final price of the jeans is $16.00
Final price of the jeans = 20 - 20% of 20
Therefore, the final price of the jeans is $16.00.
