Answer:
a² + b²
Step-by-step explanation:
(a + b)² - 2ab ← expand parenthesis using FOIL
= a² + 2ab + b² - 2ab ← collect like terms
= a² + b²
Total voters=v=80
total no. of democrats=d=65
total no. of republicans=r=15
probability of democrats=p1=65/80=0.8125
probability of republicans=p2=15/80=0.1875
probability of a democrat or a republican=p1+p2=0.8125+0.1875=1 <span />
2y = 2x + 10
y = x + 5
m = 1
Answer:
21°, 84°, 75° are the angles
Step-by-step explanation:
Total angle in a triangle is 180.
x + 4x + (5x - 30) = 180
10x - 30 = 180
10x = 210
x = 21°
Angles are:
A: 21°
B: 4(21) = 84°
C: 5(21) - 30 = 75°

See Explanation
Step-by-step explanation:
The question is incomplete, and it needs additional information before it can be answered.
However, a possible question could be that we generate an equation that has 3 variables and equals 180.
A possible question is:
<em>The sum of three consecutive numbers is 180. What is the highest number?</em>
<em />
<em>And the solution is as follows:</em>
Let the three numbers (in order of smallest to greatest) be x, y and z
So, the sum is:

Since the numbers are consecutive, then the following relationship exist:


Substitute x + 1 for y and x + 2 for z in

Solve for x


The value of the highest being is:



<em>You can generate as many equation as possible</em>
