answer:

A) The angles EA and AG are not congruent.

B) m∠F = 90°

m∠E + m∠F = 180°

90 ° + x = 180° (subtract)

x = 90°

C) Both ∠HEF and ∠AGF are congruent becuase they both have the same angle. Try and measure it using a protractor.

In isosceles triangle ABC, AB=AC.If B=55, calculate A

den301095 [7]

Answer: ∠A = 70°

because ABC is an isosceles triangle and AB = AC

=> ∠B = ∠C = 55°

=> ∠A = 180-(∠B + ∠C) = 180° - 55°.2 = 70°

Answer:

aₙ= -2n²

Step-by-step explanation:

<h2><u>Solution 1:</u></h2>

The sequence:

-2, -8, -18, -32, -50

The difference between the terms:

-6, -10, -14, -18

a₁= -2
a₂= a₁ - 6 = a₁ - 2*3= a₁- 2*(2²-1)
a₃= a₂ - 10 = a₁ - 16= a₁ - 2*8= a₁ - 2*(3²-1)
a₄= a₃- 14= a₁ - 30= a₁ - 2*15= a₁ - 2*(4² -1)
...
aₙ= a₁ -2*(n²-1)= -2 -2n² +2= -2n²

As per above, the nth term is: aₙ= -2n²

<h2><u /></h2><h2><u>Solution 2</u></h2>

The sequence:

-2, -8, -18, -32, -50
-2*1, -2*4, - 2*9, -2*25
-2*1², -2*2², -2*3², -2*4², -2*5², ..., -2*n²
aₙ= -2n²

Answer 37, 38, and 39 and make sure to answer with either the letter or with one of the answers shown! SHOW YOUR WORK PLEASE!!

ollegr [7]

Answer:

I didn't even realize until I had written all of the answers down that they are all <u><em>C.</em></u>

37 = C. <u>15%</u>

38 = C. <u>2 $x^{3}$ </u>

39 = C. <u>48</u>

Step-by-step explanation:

37: I used process of elimination to figure out which percentage of decrease it was by just multiplying 42 by each percentage until I got 6.3 which is what you need to subtract from 42 to get 35.7, so the answer is C, or 15%.

38: A coefficient is the number that is being multiplied by the variable, which in this case is "x". So whatever answer involves "2x" is the correct answer. Therefore the answer is C, or <u>2 $x^{3}$ .</u>

39: You have to add the amount of money Henry paid for painting supplies and how much profit he mad to figure out how much money he really made. 400 + 560 = 960 and he charges $20 for each painting so you need to divide 960/20 to get your answer, which is C, or 48.
