Answer: 10n^2 - 10
Step-by-step explanation:
(5n - 5)(2+2n) becomes (5n-5)(2n+2)
= (5n)(2n) + (5n)(2) + (-5)(2n) + (-5)(2)
= 10n^2 - 10
Answer:
Step-by-step explanation:
<u>Given expression:</u>
<h3>= 2(4f + 2g)</h3>
Distribute 2 to both terms.
<h3>= 8f + 4g</h3>
We can also split 8f into 4f and 4f.
<h3>= 4f + 4f + 4g</h3>
If we take 4 common
= 4(f + f + g)
<h3>= 4(2f + g)</h3>
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Answer:
a 90° clockwise rotation about the origin and then a reflection a cross the x-axis
<h3>Option A</h3><h3>3x - y = -5 is the equation of the line with a slope 3 and y intercept 5</h3>
<em><u>Solution:</u></em>
<em><u>The slope intercept form of equation is given as:</u></em>
y = mx + c ------ eqn 1
Where,
m is the slope of line
c is the y intercept
From given,
slope = m = 3
y intercept = c = 5
<em><u>Substitute m = 3 and c = 5 in eqn 1</u></em>
y = 3x + 5
3x - y = -5
Thus the equation of line is found
