Answer:
each triangle should weigh 2.5!
Step-by-step explanation:
each sides are equal. the side with only squares weighs 25. the squares on the opposite side weigh 10. 25-10 is equal to 15. there are 6 triangles. 15 divided by six gets you 2.5

Answer:
The closest measurement is 69 meters.
Step-by-step explanation:
We already know that 22 meters is the diameter and to find the circumference you need to multiply the diameter with π. We don't know π, so we are going with 3.14. When you multiply 22 and 3.14 together, you get 69.08 meters. You round the answer to the nearest meter, so it's 69 meters. So, the closest measurement is 69 meters.
The sum of the polynomials is -11x - 3y^2.
In order to find this we must first collect all like terms. To start, we'll begin with all x^2 terms.
8x^2 - 9x^2 + x^2 = 0
Since these all cancel, we're left with no x^2 term. Next we'll do x terms.
-4x - 7x = -11x
The only thing left is -3y^2, which has no alike term. so we just include that in there.
-11x - 3y^2
