Answer:
B and C | The triangles are all right triangles and they are all congruent.
Step-by-step explanation:
Haley spent $ 12....her cousin spent double....so her cuz spent $ 24
haley spent $ 12 for 2 fish...12/2 = 6 bucks per fish
so if the cuz spent $ 24....24/6 = 4.....cuz got 4 fish
haley's 2 fish + cuz's 4 fish = 6 fish in total
The problem in the picture would be
x^2+10x+21
1). Two factors of -48 => x * y = -48
=> the absolute values of the two numbers may be:
48 and 1
24 and 2
16 and 3
12 and 4
6 and 8
2). Have a differencie of 19 = > x - y = 19
That makes that the numbers be + 16 and - 3
Because (+16) * (-3) = - 48
And +16 - (-3) = +16 + 3 = 19.
3) The sum of the factors is +16 + (-3) = 16 - 3 = 13.
So the answer is the option C. 13.
100-21=79
2859(0.79)^3=1409.598
