You distribute the 30x to the equation in parenthesis
So basically you are doing (30x*x)+(30x*-3)
So you get 30x^2-90x
Hope this helps!
Answer:
16
Step-by-step explanation:
to get from 3/4 to 12/x you gotta multiple 3 times 4 which is 12 so the bottom multiple that by 4 also which 4 x 4 is 16
Answer:
X = 6 , – 2
Step-by-step explanation:
| 4x +4| - 10 =3x
4x +4 - 10 = 3x
4x - 3x = 10 - 4
x = 6
_____o___o____
– (4x + 4) – 10 = 3x
– 4x – 4 – 10 = 3x
3x + 4x = – 4 – 10
7x = – 14
x = – 14/ 7
x = – 2
I hope I helped you^_^
Well we know these two angles are congruent, so we set their angles equal to each other.
5w - 69 = w + 3
4w = 72
w = 18
Now we plug w back into one of the equations, and then multiply whatever number we get by 2.
18 + 3 = 21
21 x 2 = 42
The measure of STU is 42°
Answer:
After 7 hours Tevin will catch Enrique
Step-by-step explanation:
We have given speed of Enrique is 20 mph
Tevin left traveling after 2 hours of Enrique
Speed of Tevin is 28 mph
When Tevin catches Enrique will cover same distance
Let Enrique is traveling for t hours
Then Tevin will travel for t-2 hours
We know that distance = speed × time
So 
t = 7 hours
So after 7 hours Tevin will catch Enrique
