BRAINLIEST AND 20 POINTS PLZ HELP ASAP
DanielleElmas [232]

Answer:

Step 1: It should be m∠m + m∠n + m∠o = 180° (sum of angles in a triangle)

Step-by-step explanation:

He made the mistake in Step 1: m∠m + m∠n + m∠p = 180°

It should be m∠m + m∠n + m∠o = 180°

Then only, he can equate it with m∠o + m∠p in step 3.

So,  m∠p is the exterior angle and m∠m and m∠n are the two remote interior angles.

m∠o is the adjacent angle to m∠p. They form a linear pair.

Hence, the correct answer is Step 1.

Danielle’s chemistry professor has a complicated grading system. Each lab counts once and each test counts as two labs. At the e
Murrr4er [49]

Answer:

92

Step-by-step explanation:

Lab Scores are 84, 81, and 93

Test Scores are 89 and 94

Each lab counts once and each test counts as two labs. At the end of the semester there is a final lab that counts as three regular labs.

Total Number of Labs= (3X1)+(2X2)+(1X3) =3+4+3 =10

To recieve an A(90), the average of her scores must be 90.

Let her final lab score =b

Refer to the attached diagram

Total Score=624+3b

For her average =90

\frac{624+3b}{10}=90

Cross multiplying

624+3b =90 X 10

624+3b =900

3b =900-624

3b =276

Dividing both sides by 3

b= 92

She must score 92 in her final lab to receive an A.

create a perfect square trinomial that can be factored using special patterns. Factor the trinomial and show all work for full c
Lyrx [107]

Answer: 4x^2+12x+9


Step-by-step explanation:

A perfect square trinomial is written as ax^2+bx+c, where

first term ax^2 = square of first term of binomial

second term=bx=twice the product of both terms of binomial.

and third term 'c'=square of last term of binomial

Thus to create a perfect  square trinomial put 'a' and 'c' a square number

Let a=4 and c=9

The required trinomial will be

4x^2+12x+9

=(2x)^2+2(2x)(3)+3^2\\=(2x+3)^2.......\text{[using pattern}(a+b)^2=a^2+2ab+b^2]\\=(2x+3)(2x+3)
