Mathematics

Bumek [7]3 years ago

Answer:

The value of (x + y)³ is 1728.

Step-by-step explanation:

First, you have to find the value of x + y :

x² + 2xy + y² = 144

x² + xy + xy + y² = 144

x(x + y) + y(x + y) = 144

(x + y)(x + y) = 144

(x + y)² = 144

x + y = √144

x + y = 12

Next, the value of (x + y)³ :

(x + y) = 12³ = 1728

Help! please i’m stuck
inysia [295]
There are two equal sides of 8, which means this is an isosceles triangle. With an isosceles triangle, there are also two equal angles (30° each in this case). If angle C equals 30°, then angle B also equals 30°. Subtract angles B and C from the total degrees in a triangle.


Triangles Degrees= 180° total

Find angle A:
= total triangle degrees - < B - < C
= 180° - 30° - 30°
= 120°


ANSWER: Angle A is (B) 120°

Hope this helps! :)

If l is Parallel to m, find the value of y
BARSIC [14]

Step-by-step explanation:

1st

8x-59 + 2x-11 = 180

10x -70 = 180

10x = 180 + 70

10x = 250

x = 25

2nd

8x - 59 = 15y + 6

8(25) -59 = 15y + 6

200 -59 = 15y + 6

141 = 15y + 6

15y + 6 = 141

15y = 141 - 6

15y = 135

y = 135/15

y = 9

0.6 + 15b + 4 = 25.6 all equivelant
Mila [183]

Answer:

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

Step-by-step explanation:

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant
