1,2,and 4 are factors that 8 & 12 have in common
Answer:
A = 177.46
Step-by-step explanation:
A = 6*6+6root((6/2)^2+11.4^2)+6root((6/2)^2+11.4^2)
A = 177.46
<em>Question</em><em>:</em><em> </em><em>t</em><em>he product of two and a number, divided by five</em>
<em>Let</em><em> </em><em>the</em><em> </em><em>number</em><em> </em><em>be</em><em> </em><em>'a'</em><em>.</em>
<em>Answer</em><em>:</em><em> </em><em>2</em><em>a</em><em>/</em><em>5</em>
Soo 100.26-15% off = $85.25 and 59.99 you need to crank it up 1 so $60-10% off=$54 last add $85.25+$54=$129.25
So no she is not right
I am going to explain this using the substitution method, considering it appears to be the best in this situation.
We know (from the bottom equation) that y can equal 3x+20. Using this knowledge, we substitute the y in the top equation for 3x+20. Now, we have an equation that looks like this:
3x+20=x^2+2x
Now we need to move x to one side and then do some radicals (square roots).
Subtract the 2x on the right (since it is smaller, negatives = NONONO), which will give you
x+20=x^2
Now, we take the square root of both sides to get
rad(x+20)=x
Now we have to simplify. 20 doesn't have a square root, but 4 goes into 20, and 4 has a square root of 2. This now becomes
2rad(x+5)
This doesn't simplify any further... we have a problem... no way to isolate x as far as my knowledge goes... Sorry, can't help you any further than that, but another person or your teacher might be able to. R.I.P...
