Answer:
40, 75, 85
Step-by-step explanation:
40 squared is 1,600.
75 squared is 5,625.
1,600 + 5,625 = 7,225.
85 squared is 7,225.
Answer:
b squared + 20b+ 100
Step-by-step explanation:
multiply Using the FOIL method
first inner outer last
so
b times b = b squared
10 times b equals 10b
b times 10 equals 10b (again)
10 times 10 equals 100
add up all the answers to get the final answer
b squared + 20b+ 100
The slope is 8.5, the y-intercept is 6, y=mx+b was the original formula and m=slope and b=y-intercept :)
Answer:
125
Step-by-step explanation:
We're looking for a number that we can multiply three of the same number to get. For example, 25 is a perfect square, because 5*5 = 25.
You can test these all on your calculator, if you're allowed! Just take the third root of all of them, and if it's a whole number, you know you have a perfect cube.
The answer, though, is 125, because 5*5*5 = 125.
