Step-by-step explanation:
it should be that. all you do is multiply 615000 by 2.5
Answer:
36%
Step-by-step explanation:
1 = 100%
so 1.36 is increasing by 36%
I can only help you if you give me a lot of points
Step 1: Subtract 13 from both sides.
<span><span><span><span>x^2</span>+<span>6x</span></span>−13</span>=<span>13−13</span></span><span><span><span><span>x^2</span>+<span>6x</span></span>−13</span>=0</span>
Step 2: Use quadratic formula with a=1, b=6, c=-13.
<span>x=<span><span><span>−b</span>±<span>√<span><span>b2</span>−<span><span>4a</span>c</span></span></span></span><span>2a</span></span></span><span>x=<span><span><span>−<span>(6)</span></span>±<span>√<span><span><span>(6)</span>2</span>−<span><span>4<span>(1)</span></span><span>(<span>−13</span>)</span></span></span></span></span><span>2<span>(1)
</span></span></span></span><span>x=<span><span><span>−6</span>±<span>√88</span></span>2
</span></span><span><span>x=<span><span>−3</span>+<span><span><span>√22</span><span> or </span></span>x</span></span></span>=<span><span>−3</span>−<span>√22
</span></span></span>Answer would be
<span><span>x=<span><span>−3</span>+<span><span><span>√22</span><span> or </span></span>x</span></span></span>=<span><span>−3</span>−<span>√<span>22</span></span></span></span>
Step 1: Write down the decimal<span> divided by 1, like this: </span>decimal<span> 1. Step 2: Multiply both top and bottom by 10 for every number after the </span>decimal<span> point. (For example, if there are two numbers after the </span>decimal<span> point, then use 100, if there are three then use 1000, etc.) Step 3: Simplify (or reduce) the </span>fraction<span>.</span>
