So you would do
5×4×3= 60
and
5×4=20
so, for a 3 digit code there are 60 possibilities and for a 2 digit code there are 20 possibilities.
Answer:
IQR = 9
Step-by-step explanation:
The IQR = Q3 - Q1
So IQR = 87 -78 = 9
Answer:
A. 18x + 15
Step-by-step explanation:
For this problem, we will simply simplify the given expression:
5(4x + 3) - 2x
= 5*4x + 5*3 - 2x
= 20x + 15 - 2x
= 20x - 2x + 15
= 18x + 15

Unlike the others, the 'a' values aren't all correctly placed.
The a = -4 in the middle is correctly placed, since it's the only parabola that opens downward. This applies whenever a < 0.
The left and right items are incorrectly placed. The more narrow graph needs to have a = 1. The further 'a' is from zero, the more narrow the parabola.
<h3>In short, you need to swap the a = 1 and a = 0.25</h3>
