Answer:
To do this, you need to multiply out the expressions. This is a bit tedious, but remember like FOIL for binomials, for these trinomials you must multiply each term. If you need a step-by-step, I'd be happy to provide it. Let me know.
Once you have simplified the expression, you get
-x-9/2x-4
But, the problem stipulates that a must equal 1. We can equivalently factor out the negative sign and put it on the denominator with no change to write
x+9/-(2x-4) = x+9/-2x+4
So, seeing where each coefficient corresponds between the two expressions, you get a = 1, b = 9, c = –2, and d = 4.

LOL OK
Step-by-step explanation:
HAHAHAHAHAHAHAHAHAHAHAHA
The digit in the hundreds place has a value 10 times as great as the value in the tens place. The digit in the tens place has 1/10 the value of the digit in the hundred place
<h3>What is place value?</h3>
Place value is simply the value of each digit in a number.
For instance:
- The 3 in 350 represents 3 hundreds, or 300
- The 5 in 5,006 represents 5 thousands, or 5,000.
It is important to note that place value is the value represented by a digit in a number on the basis of its position in the number or figure.
We can deduce the following:
- The digit in the hundreds place has a value 10 times as great as the value in the tens place
- The place value of a digit at the hundredths place is 1/10 times the same digit at the tenths place
Thus, the digit in the hundreds place has a value 10 times as great as the value in the tens place. The digit in the tens place has 1/10 the value of the digit in the hundred place

Answer:
70°
Step-by-step explanation:
The tangent- chord angle is one half the measure of the intercepted arc.
intercepted arc = 360° - 220° = 140°, thus
inscribed angle = 0.5 × 140° = 70°
