Answer:
Option D: 5√5 is the correct answer.
Step-by-step explanation:
Given that:
√20 + √45
These can also be written in simplified form;
√5*4 + √5*9
We will take square root of 4 and 9.
The square root of 4 and 9 is,
√4 = 2
√9 = 3
Thus,
2√5 + 3√5
Adding the roots,
5√5
Hence,
Option D: 5√5 is the correct answer.
The formula for volume of a sphere is 3/4x(pi)x(r)^3. Where r is the radius of the sphere. V = 3/4x(3.142)x(7)^3 = 1437 mm^3
Answer:
105 hours
Step-by-step explanation:
→ Find how many days in a week
7
→ Multiply this by his gaming time
7 × 15 = 105
Answer:
7(x + 4) = 3
If you want to solve it, you can say:
7(x + 4) = 3
x + 4 = 3/7
x = 3/7 - 4
x = 3/7 - 28/7
x = -25 / 7
x = -3 ⁴/₇
x ≈ -3.57
