If we do 3 + 7 the first one it would 10 and the other one is also 10 so if we add 10+10 is would equal to 20 and if we do 20 x 5 it would 100. Your answer would be 100
Equation: 330-.255(5)=X. Multiply: .255(5)=1.275, 330-1.275=X. Subtract: 330-1.275=328.725 or 328.73 :)

Answer:
- 77x + 42
Step-by-step explanation:
note that (f ○ g)(x) = f(g(x)
Substitute x = g(x) into f(x)
f(g(x))
= f(7x - 4)
= - 11(7x - 4) - 2
= - 77x + 44 - 2
= - 77x + 42
D = {0,1,-1,2,-2,3,-3,4,-4,...}

<span>Finding an intersection of sets means listing the elements that are in both sets. </span>
<span>Finding a union of sets means listing all elements that are in either set. </span>
<span>With that in mind, </span>
<span>1. D intersect E = E because every element of E is a whole number, so it is in D also. </span>
<span>2. D intersect F = F because every element of F is a whole number, so it is in D also. </span>
<span>3. D intersect (E intersect F) First we find E intersect F = {16} because only 16 appears in E and F. Then, since 16 is also in D, D intersect (E intersect F) = {16} </span>
<span>4. We've already established that D contains everything in E and F. So when we take a union of (E intersect F) with D, we get all of D. </span>
<span>5. E union F = {1,4,9,12,14,16,18,25,36,49,64,81} because these are all the elements that are in either E or F. Intersecting with D doesn't change this list, since all are whole numbers.</span>
