Answer:combination
Step-by-step explanation: just did the assignment
Answer:
B
Step-by-step explanation:
you can use foil and the graph,
because you can see (in the graph) that the lines intersect at 1 and 4.
just use foil to help figure out which matches the slope.
something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be
-2 and -2, 2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.
<span>The answer is D.
Don't be fooled sqrt(10) goes on for many many places and if you know the 20th digit is a 9 you have a 1 in 10 chance of predicting what the next digit is. The same is true for pi and sqrt(2). The sqrt root of 16 is 4 which is rational. It could be - 4 which is still rational. The other 3 go on forever and each one has the property of unpredictability of the next digit if you know the current digit.</span>

Define their age
---------------------------------------------------------------------------------------
Let Jim be x years old
Jim = x
Father = x + 31 ← Jim is 31 years younger than the father
Grandfather = x + 70 ← Grandfather is 70 years older than Jim
---------------------------------------------------------------------------------------
Combined age is 137, find x
---------------------------------------------------------------------------------------
x + (x + 31) + (x + 70) = 137
x + x + 31 + x + 70 = 137
3x + 101 = 137
3x = 137 - 101
3x = 36
x = 12
---------------------------------------------------------------------------------------
Find their age
---------------------------------------------------------------------------------------
Jim = x = 12
Father = x + 31
Father = 12 + 31
Father = 43
Grandfather = x + 70
Grandfather = 12 + 70
Grandfather = 82
---------------------------------------------------------------------------------------
Answer: Jim = 12 ; Father = 43 ; Grandfather = 82

The square is 36 and the rectangle is 18
