A=4 b=-10 c=5
10+-√100-(4)(4)(5)/8
10+-√20/8
10+-2√5/8
x= (5+√5)/4 and x =(5-√5)/4
the parentheses just mean that it is all over 4
Answer:
Step-by-step explanation:
Our first goal is to transform these words into numbers for an expression.
Let's break it down.
<em>-7 times a number</em>
We'll assume that the number is . -7 times a number can be represented as .
<em>8 times the sum of the number and 1</em>
We can break this complex statement down.
<em>8 times </em><em>the sum of the number and 1</em>
The sum of the number and 1 will be . 8 times that will be . Since it says at the beginning <em>the sum of</em>, we add to .
<em>Is the same as the number minus 7</em>.
"Is the same" means we use an equal sign. The number minus 7 will be . So we get
Now we can solve for n by reversing the equation until we have n isolated on one side.
We end up with 8 = -7. This is not possible. Therefore, there are no real values of x that satisfy this equation.
Hope this helped!

Answer:
Length of ribbon = 40.86 inches
Step-by-step explanation:
Length of the ribbon = circumference of the dish = πD
D = diameter = 13 inches
Length of ribbon = 22/7 x 13 = 40.857143 inches
Answer:
The angles are in the ratio of 2:3 and if you convert the ratio to units, the total units of the sum of the angles is 5 units. 5 units is thus equivalent to 90 and 1 unit is equivalent to 18. One angle is 2 units and hence is 36 degrees and the other angle is 3 units and hence is 54 degrees.
