William cut two similar triangular slices of cheese with the dimensions shown below. Explain/ show work please
Answers
We need to first figure out which sides correspond to which.
13/9.29 = 1.39935 which is close to 1.4, so the sides 13 cm and 9.29 cm are corresponding sides.
8/5.71 = 1.401 which is close to 1.4, so the sides 8 cm and 5.71 cm are corresponding sides.
That leaves the 7 cm side corresponding to the unknown side.
7 cm/1.4 = 5 cm
Answer: D. 5 cm

1) if 4x+2>0 then |4x+2|=4x+2
==> 4x+2<26
==>4x<24
==>x<6
2) if 4x+2<0 then |4x+2|=-(4x+2)=-4x-2
==>-4x-2<26
==>-4x<28
==>x>-7
thus -7<x<6

So we got the function of the graph f(x) = 2^x + 1 what you will need to do first is find the y-coordinates corresponding to x=1 and x=3 which can be found by substituting into the function. After that we can find the average rate of change using y2-y1/x2-x1.
f(1)=2^1+1 which would be equal to 3
1,3
f(3)=2^3+1 which would be equal to 9
3,9
9-3/3-1=6/2
6/2=3
The average rate of change is 3.

(2k+3)(k-1)
Use the distribute property
(2k)(k)+(2k)(-1)+(3)(k)+(3)(-1)
= 12k²-2k+3k-3
= 2k²+k-3
