Answer:
-4(3n + 5).
Step-by-step explanation:
The common factor is - 4 so you take this out to give:
-4(3n + 5).
Answer: Tracey attended 70% of the basketball games.
Step-by-step explanation:
<h3>you would multiply 14 by 100</h3><h3>then you would multiply 20 by x</h3><h3>that equals 1400=20x</h3><h3>then you divide both sides of the equal sign by 20</h3><h3>and get 70%</h3>
659 divided by 8 = 82 R3.
So the answer is 82.
Hey there!
Let's first define what area means. Area is for two-dimensional shapes, and expressions how big something is and to what extent. There are formulas that can measure area because these shapes are totally flat, and there's nothing more to measure.
However, when we have three-dimensional figures such as rectangular prisms, we use surface area. Surface area measures the total area that the object takes up, and is a sum of the areas of all the faces. The formula for surface area of a rectangular prism is:
2(lw + wh + lh)
So if we had:
L = 5
W = 6
H = 3
We would have:
A = 2(5×6 + 6 × 3 + 5×3) =
2(30 + 18 + 15) =
2(48 + 15) =
2(63) =
A = 126 units cubed
Notice how it's units cubed because there's 3 dimensions.
Hope this helps!
