Surface Area=2400
Step-by-step explanation:
To find the surface area we need to use this formula: Surface Area=6a^2
Where a is the side lengths that are being provided by the cube, now we plug in 20 as a into the formula.
Surface Area=6(20)^2
Surface Area=6(400)
Surface Area=2,400
Hope I helped, have a nice day :)
Answer:
Step-by-step explanation:
You have it right it is 6^x -3
Answer:
b=-5, m= - 3/-2
Step-by-step explanation:
Slope equation is y=mx+b. Slope is finding the rise(vertical change) over run(horizontal change). In this case, -3 is our negative rise and 2 is our run. Put that into fraction form, we get negative 3/2. In the slope equation, b represents the y-intercept(where the line touches the y-axis). In this case, it is -5. Hope this helps you!
Answer:
x = 6
Step-by-step explanation:
- <em><u>Pull out like factors:
</u></em>
-4x - 13 = -1 • (4x + 13)
- <em><u>Equation at the end of step 2:
</u></em>
-178 - (-5x + -4 • [4x + 13] ) = 0
- <em><u>Pull out like factors:
</u></em>
21x - 126 = 21 • (x - 6)
- <em><u>Equation at the end of step 4:
</u></em>
21 • (x - 6) = 0
x-6 = 0
- <em><u>Add 6 to both sides of the equation:</u></em>
x = 6
