Answer:
9.9 inches
Step-by-step explanation:
if the area of the square is 49 we have and know that the base and height are equal we can express it as follows
X is one side of the square.
X * X = 49
X^2 = 49
X = √49
X = 7
by Pythagoras we can calculate the diagonal of the triangle formed by 2 sides of the square with the following expression
Y is the diagonal
7^2 + 7^2 = Y^2
49 + 49 = Y^2
√98 = Y
Y = 9.9
3(13-2a)=-3+a
39-6a=-3+a
42=7a
a=6
First, you find the probability of getting each question right individually, then you multiply the two probabilities together.
(1/3) x (1/3) = 1/9
Your answer is the second statement, Angle D is an exterior angle because it is not inside the triangle. This is because exterior angles on any shape are angles that are not included in the shape, but are rather attached on the outside. I hope this helps!
Answer:
k > 12
Step-by-step explanation:
If a quadratic equation has no real roots the values of b^2 - 4ac
( for the general form ax^2 + bx + c = 0) is negative,
So we have the inequality:
(-12)^2 - 4*3* k < 0
144 - 12k < 0
12k > 144
k > 12
