Answer:
See below.
Step-by-step explanation:
The 4 might be:
-1.9 - 3/2 , -1.8 and - 9/8.
Ex 1
the number from 1 to 100, I'll call it x
= (((x + 11) * 6 - 3) / 3 + 5) / 2 - x
= ((6x + 66 - 3) / 3 + 5) / 2 - x
= ((6x + 63) / 3 + 5) / 2 - x
= (2x + 21 + 5) / 2 - x
= (2x + 26) / 2 - x
= x + 13 - x
= 13
finally geez
Ex 2
theres 16 teams.
after a team that loses twice they're out.
1 should be left, therefor 15 teams should be out.
15 * 2 = 30,
there should be 30 or 31 games if the last team alive lost 1 game.
Answer:
No
Step-by-step explanation:
28*24=672. So, this is not even close to 800 and so isn’t reasonable.
Since AB=Bc, triangle ABC is isosceles with base AC. Then BN is height and median drawn to the base. If BN is median and AC=12 cm, then AN=NC=6 cm.
1. By the Pythagorean theorem for triangle ABN,
2. AB and BC are legs of isosceles triangle ABC. The heights drawn to the lags of isosceles triangle are congruent, so AK=CM. Consider two right triangles AKC and AKB. By the Pythagorean theorem,
Subtract from the second equation the first one:
Then
Answer: AK=CM=9.6 cm, BN=8 cm
A: no
X = 3
2x + 3
2(3) + 3
6 + 3
9
For the other one:
2(x + 3)
2(3+3)
2(6)
12
2x + 3 and 2(x + 3) are not equivalent because one has parentheses, which means you will have to do parentheses first instead of multiplication (PEMDAS rule)
Hope this helps!
