<h2><u><em>
This would be the SSS theorem.</em></u></h2>
The reason would be because the diagram shows already that the two sides are congruent to the other two sides. The line in the middle is congruent to itself. (Reflexive Property) Because we now have three congruent sides, we can say that the SSS theorem proves the two triangles congruent
Answer:
D
Step-by-step explanation:
Answer:
1. x = 2
y = 1
2. x = 3 or 6 (Mistake or typo in problem)
3. y = 13
4. x = 7
y = 15
5. x = 4
Step-by-step explanation:
1. 6x - 3 = x + 7, 5x = 10, x = 2
3y + 2 = y + 4, 2y = 2, y = 1
2. There is most likely a typo. Either 8x = 24 and x = 3 or 2x + 10 = 3x + 4 and x = 6
3. 5y -3 = 2y + 36, 3y = 39, y = 13
4. 8y + 11 + 3y + 4 = 180, 11y + 15 = 180, 11y = 165, y = 15
7x = 3y + 4 = 49, x = 7
5. 7x - 10 = 4x + 2, 3x = 12, x = 4
Answer:
x^2 -20x + 100
Step-by-step explanation:
How this works is that you multiply each number by every other number, so.
(x+a)(x+b) so you do x times x since the parenthesis multiplies them together. Then you do x times b.
Then you do a times x since a is the next number in the first pair. then you do a times b.
(* is the sign for multiplication for the sake of simplifying it and to be easier than doing something like x x x where you are multiplying x together with x.)
So in the expression (x + a)(x + b) you are basically doing
x * x + x * b + a * x + a * b
In your case, a is = to -10 and b is equal to -10
So your expression would be
x * x + x * -10 + -10 * x + -10 * -10
so x times x is x^2 and x times -10 is -10x You are doing -10 * x twice so it is -20x and -10 times -10 is 100
So the final equation would be x^2 plus -20x plus 100 or
x^2 + (-20x) + 100
which is
x^2 -20x + 100
