Answer:
Question 9: 35 Question 10: 10
Step-by-step explanation:
Use BEDMAS (Brackets Exponents Division Multiplication Addition Subtraction).
Question 9:
Start with the brackets.
10 x 4 - (7 - 2)
= 10 x 4 - (5)
Then, multiply 10 and 4.
= 40 - 5
Solve the subtraction.
= 35
Question 10:
Start with the brackets.
1 - (2 - 3) + 8
= 1 - (-1) + 8
= 1 - - 1 + 8
(Two negatives = a positive)
= 1 + 1 + 8
Add the numbers.
= 10
Uhmm what are you asking..?
Polynomial requirements
1. never divide by a placeholder
2. variable exponent has to be a whole number
3. can't have infinte terms
by 1. we eliinate 2nd one
by 2. we eliminate first one (√x=x^1/2) and 3rd one because it has an exponent in placeholder
thie leaves us with last one
f(x)=2x³-5x⁵-(2/9)x²+9
last one is answer
Its 264.
This is because its looking for the lateral surface area. And the formula for that is S=Ph.
So that means you add up the perimeter and multiply the height.
