Find the S.A of all the cubes and then add them together.
S.A = 6a²
a is the side length
S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6
Now add them all together.
54 + 24 + 6 = 84
So the total surface area is 84
Hope this helps :)

Answer:
P(5) = 26
P(-5) = 6
Step-by-step explanation:
The remainder statement tells us ...
P(x) = Q(x)·(x +5) +6
Evaluating this for x=5, we get ...
P(5) = Q(5)(5+5) +6
P(5) = (2)(10) +6
P(5) = 26
And for x = -5, we have ...
P(-5) = Q(-5)(-5 +5) +6
P(-5) = 0 +6
P(-5) = 6
6m-3m^2. You can only add,subtract, multiply, and divide the same variables. The only same variables are 2m and 4m so you add them, that's how you get 6m. -3m^2 is a different variable so you leave it alone. <span />
Answer:
c) parabola and circle: 0, 1, 2, 3, 4 times
d) parabola and hyperbola: 1, 2, 3 times
Step-by-step explanation:
c. A parabola can miss a circle, be tangent to it in 1 or 2 places, intersect it 2 places and be tangent at a 3rd, or intersect in 4 places.
__
d. A parabola must intersect a hyperbola in at least one place, but cannot intersect in more than 3 places. If the parabola is tangent to the hyperbola, the number of intersections will be 2.
If the parabola or the hyperbola are "off-axis", then the number of intersections may be 0 or 4 as well. Those cases seem to be excluded in this problem statement.
Answer:
34/39
Step-by-step explanation:
scale factor = new length / old length
34's factors are 1, 2, 17, 34
39's factors are 1, 3, 13, 39
no common factors bigger than 1 so cannot simplify
