The answer is A i believe so cause its adding 4 seats every time and you multiply 4*21 <span />
The thing that's wrong with the equation is that 2 shouldn't be multiplied by 4 but should have been added.
<h3>How to illustrate the information?</h3>
From the information given, it can be seen that the equation is:
(3x²)(-2x⁴) = 3(-2)x² × x⁴ = 6x^8
Based on the information above, this calculation is incorrect. The correct calculation will be:
(3x²)(-2x⁴) = 3(-2)x² × x⁴
= -6x^6
Therefore, the multiplication should be an addition of the power.

Answer:
5x + 3y = 95
8x + 6y = 170
x = 10 ; y = 15
Step-by-step explanation:
Let :
x = pack of juice boxes
y = pack of water bottles
Pack of juice box = $5
Pack of water bottles = $3
Amount of money spent :
5x + 3y = $95
Number of drinks purchased :
8x + 6y = 170
Using both equations ;
5x + 3y = 95 - - - (1)
8x + 6y = 170 - - - (2)
Multiply (1) by 6 and (2) by 3
30x + 18y = 570
24x + 18y = 510
Subtract :
6x = 60
x = 60 / 6
x = 10
Put x = 10 in (1)
5(10) + 3y = 95
50 + 3y = 95
3y = 95 - 50
3y = 45
y = 45 / 3
y = 15
x = 10 ; y = 15
To multiply exponents with like bases, simply add the exponents...
3^-3 × 3^4 × 3 × 3^-5 =
add exponents across, remember just 3 means 3^1.
-3 + 4 + 1 + -5 = -3
answer is 3^-3
Multiply by 4
that way you can figure out how many pages per hour were read. so 98 times 4 is 392. so it is 392 pages per hour
