7. Terrance needs to find the lateral surface area of the box shown below. Assuming that the base is the bottom of the prism, which of the expressions below will give him the correct lateral surface area?
Answers
The expression that will give the correct lateral surface area of the rectangular prism = (14.5 + 14.5 + 7 + 7)(8.6)
What is the Lateral Surface Area of a Rectangular Prism?The lateral surface area (LSA) = 2(l + w)h
Given the following:
l = 14.5 w = 7h = 8.6Lateral surface area of the prism = 2(l + w)h = 2(14.5 + 7)8.6
Lateral surface area of the prism = (14.5 + 14.5 + 7 + 7)(8.6)

I NEED HELP FAST ITS FOR A TEST (no links pls)
Part A: Explain why x = 6 makes 5x − 6 ≤ 24 true but not 5x − 6 < 24. (5 points)
Part B: What value from the set {5, 6, 7, 8, 9} makes the equation 6x + 4 = 34 true? Show your work.
Answers
Answer:
I dont know about A but the answer for B is below
Step-by-step explanation:
6x + 4 = 34 = (6x5) + 4 = 34
Answer:
Seem you are doing the same test I did! Module 7 part 2?
Anyway!
Part A: If we work through the equation 5x - 6 and substitute 6 for x then we have (5*6) - 6 = 30 - 6 = 24.
Therefore, 5x − 6 ≤ 24 is true since it means that it is equal to or less than 24.
And 5x − 6 < 24 is wrong since the equation equals 24 and is not less than 24.
Part B:
6x + 4 = 34
6x5 = 30
30+4=34
To verify: (6*5) + 4 = 34. The answer is five.

Your friend is correct.
When a figure is reflected, it is flipped. Since it is reflected on the x-axis, that is the direction it is flipped in. When flipped, the coordinate of the bottom left corner is (1, 1). When you move the figure over 5 units (which is what translating is), the coordinates are (-4, 1) which matches with the corner of the second given figure.

If the speed limit is 80 kilometers per hour, and Elena’s mom was driving 75 miles per hour, was she speeding? By how much?
Answers
First you need to converted miles into km as she was driving with miles but our speed limit is km so to maintain the balance we have to convert the measurements into one unit
Speed limit was 80km
She was driving 75 miles
We know,
1 mile = 1.609 km
So 75 * 1.609 = 120.675 km
So speeding = (120.675 - 80)
= 40.675
Therefore, she was over 40 km speed limit

Part b: 8 beads
Every inch is 4 beads.
4*2=8
Answer:
a) 56 beads
b) 8 beads
Step-by-step explanation:
12 beads take 3 inches so yes 12/3 =4 per inch
but then the necklace is 14 in long so 4 *14=56 beads
if you take off one ince per side you would take of 4 beads per side so 4*2=8 beads
