Find out what number times it's self equals the number you need to find the square root of and that's the square root
Answer:
-3
Step-by-step explanation:
if x= -3
the denominator becomes 0 and the fraction becomes undefined.
Answer:
B. m ∠ 1 = 90° and m ∠ 2 = 90°
Step-by-step explanation:
For most situations, the conjecture would probably be true, but there is one exception that makes this statement false.
When two right angles are supplementary, none of them is acute.
For an angle to be acute it needs to be lesser than 90°, and for a pair of angles to be supplementary they should add up to exactly 180°.
With a pair of right angles (90° each), their sum adds up to 180° but neither of them are acute.
Therefore, the answer is B. m ∠ 1 = 90° and m ∠ 2 = 90°
The "midpoint formula" is the same as the "average formula:"
x-coordinate of the midpoint = average of -2 and 10:
= (-2 + 10) / 2 = 4
y-coordinate of the midpoint = average of 3 and 3:
= (3+3) / 2 = 3
Thus, the midpoint of the given line segment is (4,3).
Answer:
D <u><em>Because if you substitute 4 into the equation for x and cross multiply, you get 224 = 224.</em></u>
Step-by-step explanation:
When you cross multiply, you get 14×16=224, and 224÷4=56.
