Surface area is taking the area of each face and adding it together. The equation is 2lw + 2hw + 2hl. So, for example, you'd take the length and the width to the find the area of the top. Multiply this by 2 to find the top AND the bottom. You need to end with 6 sides and all these together to find your surface area.
Answer:
C
Step-by-step explanation:
To find the x-intercept, set y to equal 0 and solve for the equation 0=-2x-2.
2=-2x
x=-1
x-int: (-1,0)
This eliminates choices B and D.
To find the y-intercept, set x to equal 0 and solve for y.
y=-2(0)-2
y=-2
y-intercept:(0,-2)
The only choice with both these values is C.

Answer:
<h2><em><u>162</u></em><em><u>0</u></em><em><u> </u></em><em><u>words</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em><em><u> </u></em>
Number of words Lucy can type in 5 minutes
= 300 words
<em><u>So</u></em><em><u>,</u></em>
Number of words Lucy can type in 1 minute

= 60 words
<em><u>Therefore</u></em><em><u>,</u></em><em><u> </u></em>
Number of words Lucy can type in 27 minutes
= (60 × 27) words
= 1,620 words
<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>Lucy</u></em><em><u> </u></em><em><u>can</u></em><em><u> </u></em><em><u>type</u></em><em><u> </u></em><em><u>162</u></em><em><u>0</u></em><em><u> </u></em><em><u>words</u></em><em><u> </u></em><em><u>in</u></em><em><u> </u></em><em><u>27</u></em><em><u> </u></em><em><u>minutes</u></em><em><u>.</u></em><em><u> </u></em>
