Answer:
1. is equilateral and 2. is scalene
Step-by-step explanation:
Isosceles triangle is when it has 2 equal angles and sides
Scalene has all different angles and sides.
Problem 1) xy means "x times y". The multiplication symbol is left out because its implied. You can write x*y if you wish. Or we can say "product of two numbers" since a product in math terms is the result of multiplication.
---------------------------------------------
Problem 2) x/y means "x divided by y" which is a fraction
---------------------------------------------
Problem 3)
Writing "x-y" is the same as saying "x minus y"
---------------------------------------------
Problem 4)
x+y is "x plus y", or we can say "the sum of x and y". The "sum" is "result of adding two or more values"
---------------------------------------------
Problem 5)
y-x is "y minus x" or we can say "x subtracted from y"
---------------------------------------------
Problem 6)
y division symbol x is essentially the flip of problem 2. We'd say "y divided by x"
---------------------------------------------
Problem 7)
x+y = 6 is "the sum of two numbers is 6". See problem 4 above.
---------------------------------------------
Problem 8)
xy = 6 is "the product of two numbers is 6". This is an extension of problem 1.
---------------------------------------------
Problem 9)
6x = y is "six times a number equals y" when translated out
---------------------------------------------
Problem 10)
y = x-6 would translate to "six less than a number is y"
where the "a number" portion is represented by x
15=7x+3-5x
15= 7x-5x + 3
15 = 2x + 3
-3 + 15 = 2x
12=2x
12/2 = 2x/2
6=x
x = 0
This is because 4 x 0 = 0 and 3 x 0 = 0. That leaves us with 5, and 5 = 5. Therefore x = 0
