Answer:
A. -12h² - 22h + 14
Step-by-step explanation:
(-4h +2)(3h +7) = -4h(3h +7) +2(3h +7) . . . . . . . (a +b)c = ac +bc
= (-4h)(3h) + (-4h)(7) + (2)(3h) + (2)(7) . . . . . . . a(b +c) = ab +ac . . . (twice)
= -12h² -28h +6h +14
= -12h² -22h +14 . . . . . . . . collect terms

Using it's concept, the probability that a card is a factor of 54 is given by:
P(Factor of 54) = 1.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, we have that there are 3 total outcomes, which are the cards 1, 2 and 3.
The factors of 54 are given as follows:
{1, 2, 3, 6, 9, 18, 27, 54}.
All the three cards are factors of 54, hence the probability that a card is a factor of 54 is given by:
P(Factor of 54) = 1.

Answer:
70.38 cm
Step-by-step explanation:
π = 3.14
Area of a circle = πr^2
394.38 = πr^2
125.598726 = r^2
r = 11.2070837 cm
Circumference = 2πr
C = 70.3804856 cm
