Label each pair of triangles with the postulate or theorem that proves the triangles are congruent.

Answers

Answer:

We can conclude that Δ GHI ≅ Δ JKL by SAS postulate.

Step-by-step explanation:

Δ GHI and Δ JKL are congruents because:

1. Their sides GH and JK are equal (9 units = 9 units)

2. Their included angles ∠G and ∠J are equal (62° = 62°)

3. Their sides GI and JL are equal (17 units = 17 units)

Now, we can conclude that Δ GHI ≅ Δ JKL by SAS postulate.

Sharon uses 72 centimeters of ribbon to wrap gifts.she uses 24 centimeters of her total ribbon to wrap a big gift she use the remaining ribbon for 6 small gifts how much ribbon will she use for each small gift if she use the same amount on each

Answers

8 centimeters a gift because when you subtract 72-24 you get 48. Then all you have to do is divide 48 by 6 because you had 6 smaller gifts then you have your answer.

She will use 8 centimeters of ribbon on each small gift.

72-24=48, 48 divided by 6 = 8

Im stuck on question 43

Answers

Ok, first things first... No, she did not do the problem correctly. This question has everything to do with order of operations which says the parentheses are the first thing to be done, followed by exponents, multiplication, division, addition, and subtraction... PEMDAS. Now, technically, her first operation that she performed was incorrect because she did the exponent first, but this really doesn't affect the outcome, so we'll overlook it for now. Her next step was to go to the parentheses, but within the parentheses, she performed the wrong operation first... She should have multiplied 2 and 3, then added 4. Instead, she committed the fatal flaw in her math and added 4 and 2 then multiplied 3. As soon as that happened, the rest of the problem was incorrect because now she's adding and subtracting the wrong number.

The notes you made yourself on the side of the problem were exactly correct and if you followed them, you would have had the correct answer. The steps should have progressed like this...

2^3 + (4 + 2 * 3) -1 =
2^3 + (4 + 6) -1=
2^3 + 10 -1=
8 + 10 - 1=
18 - 1 = 17

Of course as you get better at solving this type of equation, you can combine steps. I wrote down each individual step so you could see more clearly what was going on. Have a good night!

The answer is no. Allsion did not follow the PEMDAS rule. She added 4+2 before she multipled 2 and 3 together in the parenthesis. This is how you get the real answer.
2^3 + (4 + 2 * 3) -1
8 + (4 + 6) -1
8 + (10) -1
18 - 1
17
17 is the final answer
