the y intercept is -3 so it is choice c or a
the slope is 3/4
up 3 to the right 4
Graph A
77 degrees is the third angle
B=3 you subtract the 2 from the 23 which gives you 21 which you then divide the 21 by 7 which gives you 3
Kim bought 24 apples at the market.
She put 4 apples into each of 4 drawers in her kitchen.
She gave the rest of them to her friend.
How many apples did?
First lets find out how many she put in the drawers.
We know
4 apples per draw
4 drawers = ? apples
4 × 4 = 16
4 drawers = 16 apples
How many does she give her friend when she buys 24 apples and keeps 16 apples?
24 - 16 = amount of apples she gives her friend.
24 - 16 = 8
Kim gives her friend 8 apples.
Answer: D. 8
L=2W+2
W=(L-2)/2
A=LW, using W from above makes this
A=L(L-2)/2
2A=L^2-2L
L^2-2L-2A=0, given A=84
L^2-2L-168=0
(L-14)(L+12)=0, since L>0
L=14
The length of the rug is 14 ft
(W=(L-2)/2=6 ft)
