If you separate the triangles, you'll notice that both are literally the same triangle because all angles are the same.
ANSWER:
b) No
c) Yes
EXPLANATION:

b)
3 (-8 + 1) = 3 x -8 + 3
(3 x -8) (3 x +1) = 3 x -8 + 3 (just put left and right sides into calcu separately)
-72 = -21
Both sides are not equal and therefore it isn't a solution.
c)
3 (0.5 + 1) = 3 x 0.5 + 3
(3 x 0.5) (3 x +1) = 3 x 0.5 + 3
4.5 = 4.5
Both sides are equal and thereofre it IS a solution.
Answer:
Question 2: Option B
Step-by-step explanation:
The number of ounces and the total price for yogurt cup A is not stated, therefore, I can not answer question 1 properly.
<h3>For question 2:</h3><h3 />
Unit rate formula for price is: 
32 ounces of yogurt sell for 1.62.
So:

0.050625 ≈ 0.05
<em>Option B should be the best answer. </em>
Answer:
₹40000, 66.6%
Step-by-step explanation:
Given data
Number of boxes= 50
Cost per box= ₹1200
Total cost= 50*1200= ₹60000
Total number of mangoes in all 50 boxes= 50*100= 5000 mangoes
Cost price per mago= 60000/5000= ₹12
Selling price per mango= ₹20
profit = selling price- cost price
profit= 20-12
proft= ₹8
Total profit = 8*5000
Total profit= ₹40000
%profit = 40000/60000*100
%profit= 0.666*100
%profit= 66.6%
The way you wrote the question was a bit confusing. Also, there are two variables here. To find the one variable (the number of rolls of wrapping paper) we need to find the number of packages.
