Ppplllzzz i'll give brainliest allen is showing his work in simplifying –8.3 + 9.2 – 4.4 + 3.7. identify and explain any errors in his work or in his reasoning. write feedback to allen explaining the mistake he made and how to correct his work. step work reasoning −8.3 + 9.2 − 4.4 + 3.7 original problem 1 −8.3 + 9.2 + 4.4 + 3.7 additive inverse 2 −8.3 + 4.4 + 9.2 + 3.7 commutative property 3 −8.3 + (4.4 + 9.2 + 3.7) associative property 4 −8.3 + 17.3 simplify 5 9 simplify

Allen's work is not written properly so I have rearranged it as shown below:

Original problem) –8.3 + 9.2 – 4.4 + 3.7.

Step 1) −8.3 + 9.2 + 4.4 + 3.7 Additive inverse

Step 2) −8.3 + 4.4 + 9.2 + 3.7 Commutative property

Step 3) −8.3 + (4.4 + 9.2 + 3.7) Associative property

Step 4) −8.3 + 17.3

We can see that in step 1), Allen changed -4.4 into +4.4 using additive inverse. Notice that we are simplifying not eliminating -4.4 as we do in solving some equation. Hence using additive inverse is the wrong step.

Alen should have collect negative numbers together and positive numbers together.

Add the respective numbers then proceed to get the answer.

–8.3 + 9.2 – 4.4 + 3.7

= –8.3 – 4.4 + 9.2 + 3.7

= -12.7 + 12.9

= 0.2

Hello,

Original problem) –8.3 + 9.2 – 4.4 + 3.7.

Step 1) −8.3 + 9.2 + 4.4 + 3.7 Additive inverse

Step 2) −8.3 + 4.4 + 9.2 + 3.7 Commutative property

Step 3) −8.3 + (4.4 + 9.2 + 3.7) Associative property

Step 4) −8.3 + 17.3

Allen should have collected negative numbers together and positive numbers together.

Hope this helps (:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
