Answer:
Pythagoreas Theorem
Step-by-step explanation:
a^2+b^2=c^2
4^2+b^2=15^2
16+b^2=225
b^2= 209
14.45=b
Answer:
x = 4
Step-by-step explanation:
It is given that 
, and we have to solve the given equation for x.
Now, we have
Squaring both sides we get
![[\sqrt{(x - 3)}] ^{2} = [\sqrt{x} + 3]^{2}](https://tex.z-dn.net/?f=%5B%5Csqrt%7B%28x%20-%203%29%7D%5D%20%5E%7B2%7D%20%3D%20%5B%5Csqrt%7Bx%7D%20%2B%203%5D%5E%7B2%7D)
⇒ x - 3 = x + 6√x + 9 {Since we know the formula of (a + b)² = a² + 2ab + b²}
⇒ 6√x = - 12
⇒ √x = -2
Again squaring both sides we get
⇒x = 4 (Answer)
Answer: B
Step-by-step explanation:
1. Multiplying two negatives equals a positive.
2. Reduce the numbers with the GCF, 3.
3. Reduce the numbers with the greatest common factor, 2.
4. Multiply the fractions which would give you: 5/6
The answer is A) x = 6
<span>3(4x-3) - 19 = 8x-4
12 x - 9 - 19 = 8x - 4
12x - 8x = -4 + 9 + 19
4x = 24
4x / 4 = 24 / 4
x = 6</span>
