12(3+1)
12(4)
The number 12 times the number 4 is 48
his score was increased... so if he is now at 67 and it was increased by 7 so his first grade would have been 60.
The answer is X = 5 because first you have to take away 2x from that side so u minus 2x from 4x that gives u: 72 + 2x = 82 then you have to minus 72 from both sides and that gives you 2x = 10 once you have that you divide both sides by 2 because you want the X by itself and once you get that X = 5. Hope this helped!
Answer:
1 23/30
Step-by-step explanation:
you convet the mixed numbers into improper fractions then find the lowest common factor and combine :)
This seems like a right triangle problem.
So assuming 14 feet is the hypotenuse and 4 feet is a leg of the right triangle, we can use the pythagorean theorem (
) to solve for the height of the house, in which we shall name it x.
So, the equation is 
.
Solve for x:
16+x^{2}= 196
x^{2}= 196-16
x^{2}= 180
x = 6√5 feet
Hope this helps!
