Answer:
distribute,
Step-by-step explanation:
8+12+1 3/5x=-12
20+1 3/5x=-12
1 3/5x=8
x=5
Answer:
9in
Step-by-step explanation:
radius is half the diameter
18/2 is 9 so the radius is 9in
Answer:
1. x=4
2. x=6
Step-by-step explanation:
I've attached the graphs here:
Clearly, the solution for first one is(Reminder: the solution is the x-intercepts, when y is zero):
x=4
And the second is:
x=6

Based on the given parameters, the length of c is 8.0 units
<h3>How to determine the side length of c?</h3>
The given parameters are
Angle c = 76 degrees
Side a = 20
Side b = 13
The length of c is then calculated using the following law of sines
c^2 = a^2 + b^2 - 2absin(C)
Substitute the known values in the above equation
So, we have
c^2 = 20^2 + 13^2 - 2 * 20 * 13 * sin(76)
Express 20^2 as 400
c^2 = 400 + 13^2 - 2 * 20 * 13 * sin(76)
Express 13^2 as 169
c^2 = 400 + 169 - 2 * 20 * 13 * sin(76)
Evaluate the product and sin(76)
c^2 = 400 + 169 - 520 * 0.9703
Evaluate the product
c^2 = 400 + 169 - 504.55
Evaluate the exponents
c^2 = 400 + 169 - 504.55
So, we have
c^2 = 64.45
Evaluate the square root
c = 8.0
Hence, the length of c is 8.0 units
