Answer: x=24
Step-by-step explanation:
First, we can write this problem into a <em>mathematical equation </em>where x is you number:
<em>Eight more than 2 times your number is 56.</em>
<u>2x+8=56 </u>
Now, we can <em>solve</em> this equation for x.
<em>Subtract 8 from both sides and divide it by 2.</em>
2x=48
<u>x=24</u>

Answer:
you need to give us the equation because it is not shown
Step-by-step explanation:
B 0.05 since the thousandth digit is higher than 5, it needs to be rounded up.
Answer:
perimeter = 28.13 cm
Step-by-step explanation:
Calculate the length of a line drawn from A to C.
sin 85 = b/8, b = 7.97
cos 85 = c/8, c = 0.697
AC² =7.97² + (6 + 0.697)² = 63.52 + 44.85 = 108.37
AC = 10.41
Now you have a right triangle ADC with a known hypotenuse and one leg.
Using the Pythagorean theorem:
DC² = 10.41² - 5²
DC² = 108.37 - 25 = 83.37
DC = 9.13 cm
perimeter = 5 + 6 + 8 + 9.13 = 28.13 cm
