Y = x + 2. i hope this helped
The sum of the measures of angles in the polygon with n angles is
180°(n - 2)
We have an octagon → n = 8.
The sum of the measures of angles in an octagon is
180°(8 - 2) = 180°(6) = 1080°
The equation:
x + 139 + 140 + 125 + 116 + 152 + 2x + 143 = 1080
3x + 815 = 1080 <em>subtract 815 from both sides</em>
3x = 265 <em>divide both sides by 3</em>
<h3>x = 88 1/3</h3>
Answer: Factors (x + 2)(x + 7)
Solutions x = -2, x = -7
<u>Step-by-step explanation:</u>
h(x) = x² + 9x + 14
∧
1 + 14 = 15
2 + 7 = 9 ⇒ This sum is the coefficient of the middle term!
(x + 2) (x + 7)
To get the solutions, set each factor equal to zero and solve.
x + 2 = 0 x + 7 = 0
<u> -2 </u> <u> -2 </u> <u> -7 </u> <u>-7 </u>
x = -2 x = -7
Answer:
2/ 5
Step-by-step explanation:
From the venn diagram, find tbe probability ;
P(work | sport)
Recall :
P(A | B) = P(A n B) / P(B)
From the venn diagram :
P(work | sport) = P(work n sport) / P(sport)
P(work n sport ) = 4
P(sport) = 6 + 4 = 10
Therefore,
P(work | sport) = P(work n sport) / P(sport)
P(work | sport) = 4 / 10
P(work | sport) = 2/5
Solution:
As given Square L M NO is dilated by a scale factor of two about the center of the square to create square L'M'N'O'.
Original line of Dilation = Along P Q
New Dilated line = P'Q'
As scale factor > 1
1. Image Size > Pre image size
2. The two images will be similar.
3. Length of Dilated Line P' Q' = 2 × Length of PQ
As you can see from the diagram drawn below, Dilated line P'Q' will contain the point P and Q.
All four points P,Q,Q',P' are collinear , lie in the same line.
Option (2) dilated line P'Q' will contain the points P and Q is true.
