Answer: 9x^4
Using the rules of exponents multiply the -3 times the -3 which equals 9 canceling out the negatives. Then you have that other ^2 but you also had the other one so you still have to keep it which equals that ^4.
Answer:
2 and a half @ 2.5 inches (sorry i can't type the fraction)
Step-by-step explanation:
- english is my second language so sorry if you doesn't understand:
(1/2, 1/4)=(x,y)
based on the graph shown that each grid on the y axis represents 1/4, that is the smallest scale stood in the y axis.
this means 2 grid= 1/4 x 2 = 1/2 @ 0.5 inches.
since the '5 months-hair-length' is above about 2 grid above 2 inch:
2 inch + 0.5 inch= 2.5 inch
Answer:
100.5
Step-by-step explanation:
22/7*2^2*8
=22/7*4*8
=22/7*32
=100.5
Answer:

Step-by-step explanation:
Connect points I and K, K and M, M and I.
1. Find the area of triangles IJK, KLM and MNI:

2. Note that

3. The area of hexagon IJKLMN is the sum of the area of all triangles:

Another way to solve is to find the area of triangle KIM be Heorn's fomula, where all sides KI, KM and IM can be calculated using cosine theorem.
I saw the images that accompanied this problem.
2 circles: circle 1 has 6 slices ; circle 2 has 3 slices
Circle 1 is for Tom: you can shade 4 slices out of the 6 slices.
Circle 2 is for Liz: you can shade 2 slices out of the 3 slices.
4/6 is equal to 2/3 because when 4 and 6 are both divided by 2, they give quotient of 2 and 3, respectively.
4 ÷ 2 = 2
6 ÷ 2 = 3
