Answer:

Step-by-step explanation:
Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make
flowers in an hour. If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make
flowers in an hour.
The groups decided to work together. They can make
together in an hour and it takes them
hours. Group B took a break for 1 hour and 40 minutes (
hour), then Group B works
hours.
Thus,

Answer:
Step-by-step explanation:
a) sum of angle on the straight line TRW is 180.
Given <TRS = 2x+10
<SRW = x-10
<TRS+<SRW = 180
2x+10+x-10 = 180
3x = 180
x = 180/3
x = 60°
<TRV = 180°-(2x+10)
Substitute x = 60° into the expression
<TRV = 180-(2(60)+10)
<TRV = 180-(120+10)
<TRV = 180-130
<TRV = 50°
2) From the diagram attached <MHJ= <LHK (oppositely directed angle)
Given
<MHJ= x+15
<LHK = 2x-20
Substitute the given data into the formula to get x
x+15= 2x-20
x-2x = -15-20
-x = -35
x = 35°
Next is to get the measure of <MHJ
<MHJ = x+15
<MHJ = 35+15
<MHJ = 50°
A²b(3a² + 4ab²)
= 3a⁴b + 4a³b³
Answer:
Square
Step-by-step explanation:
check the picture below.
so as you can see, the box is simply 6 rectangles stacked up to each other at the edges.
so we can simply get the area of each rectangle and sum them up and that's the area of the rectangular prism.
