All you have to do is type it into the Desmos Scientific Calculator exactly how you see it.
Answer:
A
Step-by-step explanation:
We cannot take the square root of a negative number without using complex numbers. Because of this, both 5x and x+3 must be non-negative in order for the product to be defined.
- 5x ≥ 0 implies that x ≥ 0
- x + 3 ≥ 0 implies that x ≥ -3
Both of these are satisfied if and only if x ≥ 0 (note that if x ≥ 0, then x is automatically greater than or equal to -3). Therefore, the correct answer is x ≥ 0.
Answer:
10.6 cm to the nearest tenth.
Step-by-step explanation:
If we let one side = x. So as each side of a square are equal, and using Pythagoras we have:
x^2 + x^2 = 15^2
2x^2 = 225
x^2 = 112.5
x = √112.5
x = 10.61.
Answer:
Distributive property
Step-by-step explanation:
3(2 − 3x) + 4x = x − 7
Distribute the 3 to each term in the parentheses using the distributive property
6 -9c +4x = x-7
