Answer:
Cost of 1 = 30
So cost of 8kg apples=8*30
=240

Answer:
5(s+7) or (s+7)*5
Step-by-step explanation:
Read the question carefully when trying to do these problems. Whenever it states "sum" then you should automatically put the terms behind it (s and 7) together to add them together. This would look like s+7.
Next it says 5 TIMES the sum of the terms therefore you should put s+7 together in parentheses and multiply them by 5 so that you first have the sum of s and 7 in parentheses. This would then look like 5(s+7) or (s+7)*5.
Answer:
<u><em>(x+5) is not a factor of f(x)</em></u>
Step-by-step explanation:
Step 1 : we solve the equation x +5 = 0
x + 5 = 0 then x = -5
Step 2: we plug in -5 into f(x)
If we get zero then x+5 is a factor of f(x)
If we get a number other than zero then x+5 is not a factor of f(x)
Calculation:
f(-5) = (-5)³ − 4(-5)² + 3(-5) + 7 = - 233
Since we got -233 and not 0
Therefore ,(x+5) is not a factor of f(x)
Answer:
D
Step-by-step explanation:
w = 6 m
L = 1/2 m
Area = 1/2 * 6
Area = 3 m^2
Are you sure you have the givens correct? If you are hesitant about this answer, ask your instructor how it is done.
Edit
In that case (L = 12) then the area is
Area = 12 * 6
Area = 72
So the answer is D
