Answer:
9x^2 + 9x -70
Step-by-step explanation:
Use the distributive property to solve
(3x-7) (3x+10)
multiply 3x x 3x = 9x^2
multiply 3x(-7) and 3x(10)
add -21x + 30x = 9x
multiply -7 x 10 = -70
Answer:
x = 5
Step-by-step explanation:
set JN and NL equal to each other...
14x – 17 = 3x + 38
11x = 55
x = 5
All the angles of a triangle add up to 180 degrees.
30+39+<4= 180
69+<4= 180
Subtract 69 on both sides.
<4= 111 degrees
<1 and <4 are supplementary and adjacent. They equal 180 degrees as well.
111+<1= 180
<1= 69 degrees
I hope this helps!

Answer: 1st one
Step-by-step explanation:
Answer:
P = 0.3
Step-by-step explanation:
Here, we are to use the probability distribution in the table to calculate the probability that a children has 4 or more shoes in his or her closet
When we say 4 or more, what we mean by this is that the teenager has 4 shoes or 5 shoes
In probability expressions, when we use the term ‘or’ we are simply talking about adding the terms involved
So what we can do here is to add the probability that the teenager has 4 shoes to the probability that the teenager has five shoes
From the table that would be; 0.1 + 0.2 = 0.3
