Answer:
Step 2
Step-by-step explanation:
Fiona did mistake step 2.
Use the distributive property to multiply -3 times each term in the trinomial.
The correct result is
-3(5x^2 - 2x + 7) = -15x^2 + 6x - 21
Fiona written -6x instead of + 6x.
That's the error.
The answer is "Step 2"
Hope you will understand the concept.
Thank you.
The correct answer for this question would be option B) 18.8 units or the second option.
Answer:
The Answer is C
Step-by-step explanation:
3x-4y=5
2x+4y=-3
This equation is the answer to this problem because just by looking at it, you can immediately cancel out the y value and solve for x.
The other equations are wrong because their is extra work needed to eliminate the values.
Answer:
96 sq. cm.
Step-by-step explanation:
A "kite" has 2 diagonals, which are the "width" and "height" of the kite.
Using diagonals, the area of a kite is given by ![A=\frac{pq}{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bpq%7D%7B2%7D)
Where
A is the area
p,q are the width and height, respectively
From the problem given, p is 12 and q is 16, so the area is:
![A=\frac{pq}{2}\\A=\frac{(12)(16)}{2}\\A=96](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bpq%7D%7B2%7D%5C%5CA%3D%5Cfrac%7B%2812%29%2816%29%7D%7B2%7D%5C%5CA%3D96)
Thus, the area is 96 sq. cm
