Answer:

Step-by-step explanation:

We know that a triangle equals to 180 degrees.

(2x+24)+(4x+43)+(x^2+1)=180

the awnser to this is x=8.

You plug in 8 into x

Angle 1: 2(8+24) --> 40

Angle 2: 4(8+43) -->75

Angle 3: (8^2+1)  -->65

Check your work: add values together 40+75+65=180

Answer:

The answer is B

Step-by-step explanation:

75 + x = 90

First, Virginia had to write an equation to solve for x.

75 - 75 + x = 90 - 75

Second, Virginia used the subtraction property of equality to isolate x.

x = 15

Third, "x = 15" was the answer Virginia got after subtracting 90 and 75.

75 + 15 = 90

Finally, she had to verify her answer

Where n is the sample of size and r the combination considered, so

n=45\\r=4\\45P4= \frac{45!}{(45-4)!}\\45P4 = 3575880

There is 3575880 possibilities to make leadership structures in that committee
