Answer:
-3
Step-by-step explanation: Because it is just like saying 6-3
×=4 since you divide 3 and 12 by 3
So it would be 13-16 (4×4)
Your answer is -3
Answer:
b 48
Step-by-step explanation:
it says the sides a are 3 times larger so you are trying to find the perimeter of b so you do 144 divided by 3 since it is 3 times larger.

Answer:
In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10
Step-by-step explanation:
90 * x - 90 * 12 = 90(x - 12)
From the question, x = 10
Hence,
90(10 - 12)
(90* 10) - (90 * 12) - - - > correct evaluation
900 - 1080
= - 180
Hence, both values in the bracket, that is 10 and - 12 should be multiplied by 90. Not just 10 alone.
Answer:
Step-by-step explanation:
- cotx cos x - cot x = 0
- cotx( cosx - 1) = 0
1. <u>cotx = 0</u>
- x = π/2 + πn
- In the interval [0, 2π] we have π/2 and 3π/2
2. <u>cosx = 1</u>
- x = 0 + 2πn
- In the given interval we have 0 and 2π
<u>So the solution set is:</u>
