Ur answer is B 2x 4y hope its right
You need to bring the right to the left
2X^2-9x-x^2+20=0
So you combine and get
X^2-9x+20
(X-4)(X-5)
Cuz -4 times -5 =20 and -4+-5=-9
So solve X-4=0. X-5=0
X=4. X=5
Answer:
a) 10cm
b) 11.6 cm( approximately)
Step-by-step explanation:
Use pythagorean theorem
The exponential function is used. Use x as your variable common ratio.
This is pretty obviously
If it wasn't obvious we can find the common ratio r by dividing successive values:
5/1=5
25/5=5
125/25=5
625/125=5
<h3>What is the common ratio?</h3>
The common ratio is the number you multiply or divide by at each stage of the sequence. You can find it by dividing two consecutive pairs of terms.
That's the common ratio. We multiply by the first term, but the first term is one, so that has no effect.
