Answer:
27.5 inches.
Step-by-step explanation:
Since the wooden frame is of rectangular shape as shown below:
The length of the diagonal is AC.
Now, find AC by applying Pythagoras theory in triangle ABC
Answer:
-4
Step-by-step explanation:
take -3 to other side or add 3 to both sides
So, a=-7+3
=-4
Answer:
4
Step-by-step explanation:
12n - 2n = 10n
10n = 40
40 divided by 10 = 4
n = 4
Answer:
Angle 3= 37 degrees, Angle 2 = 143 degrees, Angle 4= 143 degrees
Step-by-step explanation:
Angle 3 is across from Angle 1 so they are equal to each other. Now to find Angles 2 and 4, cover angles 2 and 3 with your hand so you are just looking at 1 and 4, they are on a line. Lines are 180 degrees, so since angle 1 we know is 37 degrees, then 180-37= 143 degrees for angle 4. Now, 2 and 4 are opposites of each other, and share the same value of 143 (just like how we found angles 1 and 3 to be equal bc they are across from each other)
Answer:
Graph D
Step-by-step explanation:
Move the constant to the opposite side of the equation and group terms that include the same variable.
g(x) + 1 = x^2 + 2x
Finish the square. Remember to keep the equation balanced by using the same constants on both sides.
g(x) + 1 + 1 = x^2 + 2x + 1
g(x) + 2 = x^2 + 2x + 1
Rewrite as perfect squares
g(x) + 2 = (x + 1)^2
Equation in vertex form:
g(x) = (x + 1)^2 - 2
The vertex:
(-1, -2)
