A new Neighborhood Activity Complex is being built-in

Mathematics
1 answer:
Anestetic [448]3 years ago
7 0

Step-by-step explanation:

L = 2W - 8

P = 230 yd

P = 2×(L+W)

230 = 2× (2W - 8 + W)

230 = 2× (3W-8)

230 = 6W-16

6W= 230+16

6W = 246

W = 246/6

W = 41

L = 2(41) -8

= 82-8

= 74

so, the dimensions of the playing field:

the length = 74 yd

the length = 74 ydthe wide = 41 yd

Find two additional roots of P(x)=0.<br><br> 13+sqrt 3 and 7i
vova2212 [387]
So, x = 13, x = √3 and x =7i.

now, recall that for an EVEN radical, there are two possible roots, namely is say √3 is say hmmm some value "a", that means that a*a = √3, however, -a*-a is also √3, therefore, ±√3 are two valid values, and therefore -√3 is another one.

now.... keep in mind that, complex solutions or roots, never come all by their lonesome, their sister is always with them, the conjugate, so, for 7i or namely 0 + 7i, her sister is always around, 0 - 7i, which is the other root.

Answer:

A linear pair is a pair of angles that share a side and a base. In other words, they are the two angles created along one line when two lines intersect. Linear pairs are always supplementary.

Answer:

The answer to your question is:  B and D are correct

Step-by-step explanation:

Remember that the sum of the internal angles in a triangle equals 180°.

The sum of supplementary angles equals 180°

Then

                (6x + 1) + (4x + 5) + [180 - (8x + 30)] = 180

                6x + 1 + 4x + 5 + [180 - 8x - 30] = 180

                10x + 6 + 150 - 8x = 180

                2 x = 180 - 156

                2x = 24

                x = 24/2

                x = 12

∠JKL = 4(12) + 5 = 48 + 5 = 53

∠KJL = 6(12) + 1 = 72 + 1 = 73

∠KLJ = 180 - 73 - 53 = 54

∠KLM = 126
