Answer:
Step-by-step explanation:
3x^2 + 5x + 25 when x = 3
= 3(3)^2 + 5(3) + 25
= 3(9) + 15 + 25
= 27 +15 + 25
= 67
Answer:
Step-by-step explanation:
you just multiply by 5 to get your answer
Answer:
Difference in area of the last square and the initial square = 440 cm²
Step-by-step explanation:
Length of the side of a square = 1 cm
Area of the square = (side)² = 1 cm²
Addition of side length every minute = 2 cm
After x minutes length of each side of the square = (1 + 2x) cm
If x = 10 minutes
Length of each side of the square = [1 + 2(10)]
= 21 cm
Area of the square after 10 minutes = (21)²
= 441 cm²
Therefore, difference in area of the last square and area of the initial square
= 441 - 1
= 440 cm²
Answer:
0.35
Step-by-step explanation:
this is the answer.........
It appears Jake said 5-2 = 3 for the denominator portions. This is not correct. In order to subtract fractions, the denominators must be the same and they stay the same the entire time. Only the numerators (aka stuff up top) are being subtracted.
Currently 3/5 - 1/2 cannot be subtracted since the 5 and 2 are different denominators. But we can say this:
3/5 = 6/10
1/2 = 5/10
and then from there, we can say:
3/5 - 1/2 = 6/10 - 5/10 = (6-5)/10 = 1/10
So in short,
3/5 - 1/2 = 1/10
