The pythagorean theorem states that a^2+b^2=c^2.
3^2 is 9.
9+9=18
The square root of 18 is approximately 4.24.
a.
b.
c.4.24
Answer:
15
Step-by-step explanation:
Plug in 3 as x:
3x + 6
3(3) + 6
9 + 6
= 15
So, the simplified expression if x = 3 is 15

Answer: (x+1)(x+3)</h3>
===================================================
Explanation:
Let's assume it factors into (x+a)(x+b)
The goal is to find the two numbers a and b.
FOIL out (x+a)(x+b) to get x^2+(a+b)x+ab
Note how a+b is the middle term and ab is the last term.
In the original expression, 4 is the middle term and 3 is the last term.
So we need to find two numbers that
There are two ways to multiply to 3 and they are
- 1 times 3 = 3
- -1 times -3 = -3
But only the first way has the factors add to 4. So that means a = 1 and b = 3.
Therefore (x+a)(x+b) = (x+1)(x+3)
And x^2+4x+3 = (x+1)(x+3)
Answer:
I beliive it is 16, but haven't done this in a bit haha
Step-by-step explanation:
So bisect means to "split in half" aka segment BD is directly in the middle of triangle ABC. This means we can look at the half of the triangle we know (ABD). We see a 16, so therefore x should be 16.
(again, hopefully I am correct)
Answer:6.7
Step-by-step explanation:
5t-17.2=16.3
5t=16.3+17.2
5t=33.5
5t/5t=33.5/5
t=6.7
