Answer:
-14w²-7w+1
Step-by-step explanation:
(–7w2 – 2w – 1) – (–5w2 + 3w – 2)
-14w²-2w-2w-1 +10w²-3w+2
combine the like terms
-14w² + 10w² - 2w-2w-3w+2-1
-4w²-7w+1
Its intersection would be at the centre of the sphere, each line being perpendicular to the other, probably
Answer:
Option C
Step-by-step explanation:
40/10 simplifies to 4.
40/100 simplifies to 0.40.

Answer:
h = 2A/b
Step-by-step explanation:
Step 1: Write out triangle formula
A = 1/2bh
Step 2: Multiply 2 on both sides to get rid of fraction
2A = bh
Step 3: Divide both sides by <em>b</em> to isolate <em>h</em>
2A/b = h
Step 4: Rearrange
h = 2A/b
Answer:
There would be no solution
