In this item, it can be seen that from an expression of,
(4 + 5i) + (-3 + 7i)
Aiko transformed the equation by factoring out the i's from the expression and wrote it as,
(4 + 5)i + (-3 + 7)i
Now this is wrong because i there is not a variable but a notation that 5 and 7 are imaginary numbers. In fact, she cannot factor out the i's because it is not present in both -3 and 4. The answer therefore to this item is the last sentence, "Aiko incorrectly used the distributive property by combining ..."
Answer:
the numbers are 85 and -31.
Step-by-step explanation:
first, let the numbers be x and y.
so by question we have,
x+y=54.......(I)
x-y=116......(I I)
now, solve it through elimination method,
x+y=54
x-y=116
here, y and y cancelled out and we get,
or, x+x=54+116
or, 2x=170
or, x=170/2
therefore, x=85
now put value of x in any equation. let's put in eqn (I), we get,
or, x+y=54
or,85+y=54
or, y=54-85
so, y= -31
therefore, the numbers are 85 and - 31.
Answer:
1 yd=36 inches
1 ft=12 in
36 x 7=252 inches
2x 12=24
252 +24=276 inches
hope this helps
have a good day :)
Step-by-step explanation:
The correct answer is option A which is ABCD ≅ A'B'C'D'.
<h3>What is translation?</h3>
The process of changing the location of the image on the coordinate system will be known as the translation.
Quadrilateral ABCD is rotated at 145° about point T. The result is quadrilateral A'B'C'D'.
ABCD ≅ A'B'C'D'is correct Since the quadrilateral remains the same even after rotation of 145 degrees. Its corresponding sides and angles will remain the same.
Thus ABCD is congruent to A'B'C'D'.
