Use the expression 5(6 + 4x) to answer the following:

Part A: Describe the two factors in this expression. (4 points)

Part B: How many terms are in each factor of this expression? (4 points)

Part C: What is the coefficient of the variable term? (2 points)

(Help!!!)

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

here is something that relies on definition of subset and logical implication:

the definition of a subset is that if there are two sets a and b of a certain universe, a is a subset of b if every element in a is also an element of b, i.e.

  for all x, if x ∈ a, then x ∈ b

the empty set ∅ has no elements, so if a is any set from any universe, then ∅ ⊆ a (∅ is a subset of a) is true if

  for all x, if x ∈ ∅, then x ∈ a

clearly, x ∈ ∅ is always false because the empty set has no elements. so this implication is always true (remember that logical implication is only false if a true premise implies a false conclusion), thus making ∅ ⊆ a always true.
