Answer:
5$??.
Step-by-step explanation:
If a magazine was 5$, 25-5= 20. So then, 20÷4= 5. There fore an eraser costs 5$.
In scientific notation :
32 million miles is 3.2 x 10 ^7 miles.
I got 1.5, but I could be wrong.
Answer:
B (5 sqrt10)
Step-by-step explanation:
If the hypotenuse is 17, and a leg is 8, that makes the other leg equal to sqrt((17^2)-(8^2)) = sqrt(289-64) = sqrt(225) = 15.
Because you subtract 3 from the leg with length 8, that makes the smaller triangles leg 5. That makes the hypotenuse sqrt(5^2 + 15^2) = 5sqrt10
I'm guessing you typoed for B and meant 5sqrt10, so the answer is B
The answer is B, 4(x-5)(x+3)
