So when you opened up the parenthesis on the right side of the question, you added -2 to 5 instead of multiplying. Since there is no addition sign in between -2 and the parenthesis, it should be multiplication, so -2x + -10.
So now the answer would be 10 = -10.
Which leads me to believe that this question wasn't written correctly because 10 does not equal -10 for sure.
Answer:
After 10 years the ratio will be 10500: 500000
X² = 16
the way to isolate your x variable is to square root both sides
√x² = √16
x = <span>± 4
so your answers are 4 and -4</span>
Answer:
1 cubic centimeter is the volume
Step-by-step explanation:
the surface area is 6
6 = 6a^2
1 = a^2
1 = a
L * W * H = ?
1 x 1 x 1 = 1
1 is the volume
have a good day!
You are trying so solve
<span><span>3^x</span>=8</span>
and since 8 is not an integral power of x you need a calculator.
it is <span><span>ln(8)/</span><span>ln(3)</span></span>
or
<span><span><span>log(8)/</span><span>log(3)</span></span></span>
