Answer: Valid
Step-by-step explanation:
That's right, if they are both right angles, they are both 90 degrees. That means they're equal.
Answer:
C
Step-by-step explanation:
Pythagorean theorem states that a^2 + b^2 = c^2. Let the length of the legs be x, so 2x^2 = c^2. c is the hypotenuse, which means that 2x^2 = 64. Divide both sides by 2, and we get x^2 = 32. Square root both sides and we get sqrt 32 or 4 * sqrt 2.
Answer:
180 - 61 = 119
Step-by-step explanation:
So from A to D it is 180 degrees so just have to subtract 61 from 180 for an answer.
Answer:
I won't be able to give you a numerical answer but that's not what your question's asking anyway. Just put a dot at the coordinates (0,-3) and one at (-2,3) and connect them. That's your first line. For the second question put a dot at the intersections (0,1) and one at (-4,-3) and connect them. You should be able to find a point where the two lines intersect. That's the point you need. If you still can't find it, then continue the lines or message me at riztofu on insta. I'll solve your question then.
Step-by-step explanation:
Answer:
-a² + 2ab + b² is your answer, or C).
Step-by-step explanation:
b(a + b) -a (a - b)
Distribute b to (a + b), and -a to (a - b)
b(a + b) = ab + b²
-a(a - b) = -a² + ab
Simplify. Combine like terms.
(-a² + ab) + (ab + b²) = -a² + 2ab + b²
-a² + 2ab + b² is your answer, or C).
