Use PEMDAS method to execute operations in the following order:

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

First equation:

12 + (38 - 18)2 = 12 + 20 × 2 = 52

Second equation:

(12)2 - 6(2 - 23) = 24 - 6(-21) = 24 + 126 = 150

Hope this helps.

Basic Definitions of Geometry

A collinear set of points is a set of points all of which lie on the same straight line.
A noncollinear set of points s a set of three or more points that do not all line on the same straight
line.
A Line has no end points.
A Ray has one end point.
. Line Segment has two end points
Congruent segments are segments that have the same measure.
The Midpoint of a line segment is a point of that line segment that divides the segment into two
congruent segments.

The Bisector of a line segment is any line, or subset of a line that intersects the segment at the midpoint.
An Angle is a set of points that is the union of two rays having the same endpoint.

Pls help I don't understand this

<h3>Answer:</h3>

By angle bisector property,

11x + 23 = 8x + 35
11x - 8x = 35 - 23
3x = 12
x = 4°

So, m∠ABD = 8x + 35

8 × 4 + 35
32 + 35 = 67°

m∠CBD = 11x + 23

11 × 4 + 23
44 + 23 = 67°

m∠ABC = 67° + 67° = 134°

X=1/16y^2 the directrix of the parabola is

yan [13]

To solve this problem you must apply the proccedure shown below:

1. You have the following equation of a parabola, given in the problem above:

x=1/16y^2

2. Then, based on the graph attached, you have:

p=y^2/4x
p=8^2/(4)(4)
p=64/16
p=4

3. The directrix is:

directrix=h-p
directrix=0-4
directrix=-4

The answer is:-4
