Recognizing the no-solution case algebraically need geometry help!!

Dmitrij [34]

Answer:

"The values for y are square roots of negative numbers"

Step-by-step explanation:

The steps shown are correct. But at the end we can see that we have to "take the negative square roots".

This means we have to take the square root of -1. In the real number system, we CANNOT take the square root of any negative number. Hence, there is NO SOLUTION to the system.

2nd answer choice, "The values for y are square roots of negative numbers", is right.

Which big these flags will have the greatest area? Why?

svetoff [14.1K]

<h2>Question 1:</h2>

The area of flag b is the greatest.

Explanation:

Area of triangle = $\frac{1}{2}base*height$

Area of parallelogram = base * height

For flag A:

It is a triangle with base = b and height = a

Area of flag A = $\frac{1}{2}a*b$ square units

For flag B:

It is a parallelogram with base = a and height = b

Area of flag B = a*b square units

For flag C:

It is a triangle with base = b and height = a

Area of flag C = $\frac{1}{2}a*b$ square units

From the above, we can conclude that the area of the parallelogram (flag B) is the greatest

<h2>Question 2:</h2>

The perimeter of flag C is shorter than that of flag A

Explanation:

Perimeter is the sum of the three sides of the figure

For flag C:

The three sides are given as a, b and c

Therefore, perimeter of flag c = a + b + c units

For flag A:

We are given two sides as b and c and we are given that the height is a

We know that in the given flag, the third side (the unknown slant one) will be longer than the height of the height of the triangle

Therefore, the third side = a + k where k is a constant

Therefore, perimeter of flag A = a + b + c + k units

From the above, we can conclude that the perimeter of flag C is shorter

Hope this helps :)
