Answer:
x = 1, y = -2, z = 3.
Step-by-step explanation:
x + 2y + 2z = 3 A
2x -2y - z = 3 B
x - 2z = -5 C
If we add equations A and B we eliminate y:
3x + z = 6 E
Multiply E by 2 :
6x + 2z = 12 F
Adding C and F we get:
7x = 7
x = 1.
Plug this into equaton C:
1 - 2z = -5
-2z = -5 - 1 = -6
z = 3.
Now plugging x = 1 and z = 3 in equation A:
1 + 2y + 2(3) = 3
2y = 3 - 1 - 6 = -4
y = -2.
Ratios of Area of the two squares = 25:9
So then let the areas be A1 = 25A and A2 = 9A, A is common element
Side of the smaller area S2 = 30 meters
Area of the smaller square A2 = 30 x 30 = 900
We have area of smaller square as 9A = 900 => A = 100
Area of the large square = 25A = 25 x 100 = 2500.
Hence S1^2 = 2500 => S1 = 50 meters which is 20 meters longer than the
side of the smaller square.
<u>Answer:</u>
"It is used when you solve an equation in algebra" is the untrue statement.
<u>Step-by-step explanation:</u>
"It is used when you solve an equation in algebra."
When you solve an algebra problem, you are not using deductive reasoning. You are using the information in front of you to correctly answer.
"It is used to make broad generalizations using specific observations."
This is exactly what deductive reasoning is, you are making generalizations and coming up with your own conclusions through observation.
"It is used to prove basic theorems."
This is also true, you can use deductive reasoning by using your specific observations and drawing conclusions to prove the theorems.
"It is used to prove that statements are true."
Using your own observations, you can draw your own conclusions to prove what you are saying is factual.
Here you go!!! I hope this helps
