❖ The area of a square with lengths of 7 inches is 49 inches.
In a square, all sides are equal so if one side is 7 inches, the rest of the sides are 7 inches. You multiply 7 x 7 because you only need 2 sides to find the area because the area of a square is l x w. (If another sides length is stated, that is the length that you will use.

-3 (-4 + -x ) = (-4(x) × 2 ) + 6
-3 (-4-x) = (-4x × 2) + 6
-12 + 3x = -8x + 6
3x - 12 = 6 - 8x
add 8x on both sides
11x - 12 = 6
add 12 on both sides
11x = 18

Answer:
16.35
Step-by-step explanation:
Using an inverse normal distribution, we can calculate the z score given the percentile, which can then be used to find our value.
First, we can use an inverse normal distribution calculator to figure out that the z score given the 75th percentile is 0.674.
Next, we know that the z score is (observed value - mean) / standard deviation. We can plug our values in to get
Rounding, we get x = 16.35 as our answer
Answer:
244 degrees
Step-by-step explanation:
Since one angle APE is 90 degrees, that means line segments AD and BE are perpendicular bisectors.
Since both segments go through the center, that means all the angles are central angles.
Since angle APE is 90 degrees, that also means that angle EPD is 90 degrees.
33k -9 = 90
33k = 99
k = 3
Since we know k we can substitute it to find angle CPD.
20 k + 4 = 20*3 + 4= 60+4= 64 degrees.
Central angles equal angles of arcs, so we can and angles APE, EPD, and DPC to find the measure of major arc CAD.
64+ 90 +90 = 244 degrees
