Answer
33
Step-by-step explanation:
11 of the faces is a square.
\begin{aligned} \text{Area of a square} &= \text{side} \cdot \text{side}\\\\ &= 3 \cdot 3\\\\ &= {\blueD{9}} \\\\ \end{aligned}
Area of a square
=side⋅side
=3⋅3
=9
Hint #22 / 4
444 of the faces are triangles. Each triangle has the same base and height.
\begin{aligned} \text{Area of a triangle} &= \dfrac12 \cdot \text{base} \cdot \text{height}\\\\ &= \dfrac12 \cdot 3 \cdot 4\\\\ &= 6 \\\\ \end{aligned}
Area of a triangle
=
2
1
⋅base⋅height
=
2
1
⋅3⋅4
=6
The total area of these 444 triangles is 4 \cdot 6 = \greenD{24}4⋅6=244, dot, 6, equals, start color #1fab54, 24, end color #1fab54.
Hint #33 / 4
Let's add the areas we found to find the surface area.
\begin{aligned} \text{Surface area} &= \blueD{9}+ \greenD{24}\\\\ &= 33\\\\ \end{aligned}
Surface area
=9+24
=33
Hint #44 / 4
The surface area of this square pyramid is 333333 units^2
2
squared.
Hi! X = 2
Because 4 + 10 = 14. 16-14 = 2
x =2
Does this make sense?

Answer:
$160
Step-by-step explanation:
28 bags cost $140
4 bags will serve 5 guests
Number of bags that will serve 40 guests:
(40 /5) * 4bags
8 * 4 bags = 32 bags of candy
A bag of candy will cost :
$140 / 28 = $5
Cost of 32 bags :
Cost per bag * 32
$5 * 32 = $160
Hello!
Say that n is the number. There are two parts to this statement. The first part is "four less than three times a number", and the second is "is three more than two times the number. An expression fitting the first part will go on the left side of the equation, and the second part will go on the right.
Look at the first part. "Four less than three times a number". The first thing being done here is the <u>three times a number.</u> This would be 3n, as it is 3 times n. Now, there is the <u>four less</u> part. You would therefore have to subtract 4 from 3n, to get 3n - 4.
Now the second part. "Is three more than two times the number". The first thing being done here is the <u>two times the number</u>. That would be 2n. The next is "is three more than". If the other side is three more than 2n, then you must add 3 to 2n to make them equivalent. Therefore, it would be 2n + 3.
Now, set them equal to each other, and solve.
3n - 4 = 2n + 3
3n - 2n = 3 + 4
n = 7
Therefore, your number is 7.
Hope this helps!
