we are given
three consecutive even integers
Let's assume
first even integer is x
second even integer is x+2
third even integer is x+4
sum of the first two consecutive even integers is equal to three times the third so, we can get equation as
now, we can solve for x
so, we get
first integer is -10
second integer is -10+2=-8
third integer is -10+4=-6.................Answer
Answer:
8x squared
Step-by-step explanation:
all you do is multiply the 4 and 2 to get the 8 and the x's multiply together causing it to square it making it 8x squared
Answer:
The Pythagorean theorem should help you out. Since you already know two sides of the triangle, you can do a^2 + b^2 = c^2
So in this problem, 16.5^2 + 9.2^2 =
272.25 + 84.64 = 356.89
Pasty you would take the square root of 356.89 and you would get x = 18.89 or 18.9 rounded to the nearest tenth
You can check your work by the Pythagorean theorem once more. 16.5^2 + 9.2^2 = 18.9^2 and you should get the same approximate answer (it will be a little bigger because you rounded)
Answer:
y=4
Step-by-step explanation:
1.- subtract 1/4 y from both sides
2.- add 12 to both sides
3.-divide both sides by 2
