20 - 21 - 10 + 5x +1= 0
5x = 10
x = 2
<span>The correct answer is 216x</span>⁶<span>y</span>⁵<span>.
Explanation:
The first thing we do is raise the last monomial to the third power.
(4xy)(2x</span>²<span>y)(3xy)</span>³
<span>=(4xy)(2x</span>²<span>y)(3</span>³<span>x</span>³<span>y</span>³<span>)
=4xy(2x</span>²<span>y)(27x</span>³<span>y</span>³<span>).
Now we can multiply the first two monomials. When we multiply powers with the same base, we add the exponents:
8x</span>³<span>y</span>²<span>(27x</span>³<span>y</span>³<span>).
We multiply these last two monomials, again adding the exponents:
216x</span>⁶<span>y</span>⁵<span>.</span>
Answer:
75 minutes
Step-by-step explanation:
Assuming that Clare will not take a break throughout the session
10 books=1 minute
750 books= x minutes
Cross multiplying to find the value of x
10x books=750 books minutes
Making x the subject
x=750 books minutes/(10 books)
x=75 minutes
This translates to 1 hours and 15 minutes
Therefore, Clare will require 75 minutes
Slope = (-2 - 10)/(12 + 6) = -12/18 = -2/3
y = mx + b
10 = -2/3(-6) + b
10 = 4 + b
b =6
equation
y = -2/3x + 6
<span>x-intercept when y = 0
</span>-2/3x + 6 = 0
-2/3x = -6
x = 6 (3/2)
x = 9
answer is <span>d.9</span>
CAB=17 degrees
CAB is the first section to the left. Point A is the center of your measurer, and the C and B are the end points of the angle. To find out the measure of angle CAB, you count the marks made in black between C and B, which results in 17 degrees—three less than the long mark at 20.
