It’s -7 because -7^2= 49-35-9=5
Answer:
A quadrilateral become square if all the sides joining the co-ordinate of quadrilateral is equal
Step-by-step explanation:
Here the given co-ordinate of quadrilateral are
G (3, -1) O(1, -6)
L(-4, -4) F(-2, 1)
Line GF = 
GF = 
Similarly for line OG, OL, FL
OG = 
OG =
OL = 
OL =
And
FL = 
FL =
all the sides of quadrilateral GF, OG, OL, FL all equal to
As all the sides are equal so quadrilateral become square Answer
An easy way to think of this when you solve this, is to remember that all the angles in a triangle add up to 180 degrees. Therefore, the equation would be
(3x + 10) + (2x + 10) + 45 = 180. By the way, since the angles D and B are across from each other they are congruent. Now, let’s start solving it:
(3x + 10) + (2x + 10) + 45 = 180
(5x + 20) + 45 = 180
5x + 65 = 180
5x = 115
x = 23
Answer: 2.2532
Step-by-step explanation:
From the table attached :
Expected probability = sum of p(x) * x ; wher P-X) is the probability of x
E(p(x), x) = (0*0) + (1 * 0.06) *(2*0.1) + (3 * 0.16) * (4 *0.16)+ (5*0.26) * (6 *0.08) + (7 * 0.13) + (8 * 0.05)
Pp(x) * x) = 2.2532
Therefore, the expected value of the distribution is 2.2532
A cube is a 3d object bounded by 6 square faces.
Each side of the display case is 3 times longer than the width of the artifact.
width of the artifact = w
side of the cube = 3w
<span>a. Write an expression for the volume of the case.
volume of a cube is the measure of its side raised to the power of 3.
Volume = (3w)</span>³
<span>Volume = 27w</span>³<span>
</span>
