You are gonna use the distributive property.
4(2.5g - 4) + 3(1.2g - 2)
So you are going to multiply 4 with everything inside the first set of parenthesis and your gonna multiply 3 with everything insides the second set of parenthesis.
4 x 2.5g - 4 x 4 + 3 x 1.2g - 3 x 2
10g - 16 + 3.6g - 6
You wanna combine like terms:
10 - 3.6g + 16 - 6
6.4g + 10
You answer is 6.4g + 10.
Hope this Helps!!
Answer:
B
Step-by-step explanation:
Variance can be said to be a measure of dispersion for a random sample.
Variance = pq/n
When given the variance, we can find the standard deviation.
Standard deviation = √variance
= √pq/n

Answer: 294cm
Step-by-step explanation:
The volume of a oblique cylinder is given by:
Volume= πr^2h
where
π = 3.14
r = radius
h = height
Radius= diameter/2 = 6/2 = 3
We have all the values, so we put it in the formulae so we can get the answer.
Volume= πr^2h
= 3.14 × 3 × 3 × (0.4 × 26)
= 294cm
