Answer: B. $3.15
Step-by-step explanation: Hi! So first things you want to add all the things he bought together and then subtract it from the $20. I’m sorry if this isn’t right.
The answer is C. Factor the equation: 2x^2 + 10x + 12 which gives you............. 2(x + 2) (x + 3), and then cancel out (x + 3) because dividing (x + 3) by itself gives you one and the remaining term is 2(x +2) which is the same as 2x +4.
Answer:
Step-by-step explanation:
1.5x^2+6x+.... so that it can be rewritten in the form a(x+b)^2
Let .... be C
1.5x^2+6x+C
=1.5(x^2+4x+(C/1.5))
Compare above with 1.5(x+2)^2 = 1.5(x^2+4x+4)
C/1.5=4
C=6
So the expression should be 1.5x^2+6x+6
It can be rewritten to 1.5(x+2)^2
Answer:
The probability that Jordan does not selects a salamander is 
or 0.55
Step-by-step explanation:
First, we will have to add up all of the number of animals.
55 + 33 + 12 = 100
Now, we find the ratio of 55 and 100 to get the probability.
55 / 100 = 11 / 20
So, the probability that Jordan does not selects a salamander is or 0.55
We know, radius = diameter / 2 = 18 / 2 = 9 in.
Circumference = 2πr = 2π(9) = 18π = 18 * 3.14 = 56.52 in.
Hope this helps!
