P = 2a + b + c
Subtract 2a + b on both sides
c = P - (2a+b)
c = P - 2a - b
Hope that helps :)
Answer:
b. false
Step-by-step explanation:
when multiplying matrixes the number of columns of the first matrix must be equal as the number of rows of the second matrix, and since here matrix A has 4 columns but matrix B has 5 rows they can't be multiplied

Some people are lucky their question stays for more than a week. And their question is useless
Unfair. Always
Answer:
Step-by-step explanation:
Applying BODMAS here;
We first solve what is in the brackets:
9x - 81 -3 = -8x - 16
We then put the like terms together:
9x + 8x = -16 + 81 + 3
We then do the addition:
17x = -16 + 84
We then do the subtraction:
17x = 68
Simplifying this gives:
x =
= 4
The sector area and the arc length are 34.92 square inches and 13.97 inches, respectively
<h3>How to find a sector area, and arc length?</h3>
For a sector that has a central angle of θ, and a radius of r;
The sector area, and the arc length are:
--- sector area
---- arc length
<h3>How to find the given sector area, and arc length?</h3>
Here, the given parameters are:
Central angle, θ = 160
Radius, r = 5 inches
The sector area is
So, we have:

Evaluate
A = 34.92
The arc length is:

So, we have:

L = 13.97
Hence, the sector area and the arc length are 34.92 square inches and 13.97 inches, respectively
