A = (1/2) b* h
OR
A = (b*h)/2
A = (8* 2)/2
A = 16/2
A = 8 yd^2

Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- a straight line contains 180°
<h3>let's solve:</h3>
according to the question
7x+x+20=180
=>8x+20=180
=>8x=160
therefore
x=20

What you want to do for each of those is follow the formula, y-y[1]=m(x-x[1]). When I say y[1] and x[1], I mean the x and y values given. So the first one would be y-4=-3(x-(-1)). Then you solve for y by distributing the -3 to x and +1 (+1 because two negatives make a positive), making the equation
y-4=-3x-3. Then you subtract the 4. Answer #1. y=-3x-7.
#2.
y-1=1(x-4)
y-1=x-4
y=x-5
#3.
y-2=2(x-(-1))
y-2=2x+2
y=2x+4

Answer:
1. ÷ --->
2. --->
3. --->
4. -->
Step-by-step explanation:
Given that:
1.
Thus,
÷ = ÷
Flip the 2nd function, Q(x), upside down to change the process to multiplication.
2. =
Make both expressions as a single fraction by finding, the common denominator, divide the common denominator by each denominator, and then multiply by the numerator. You'd have the following below:
3. =
4.
