Mathematics
1 answer:
Basile [38]3 years ago
8 0

Answer:

D

Step-by-step explanation:

7 - z = 3 + z + 4 - 2z

7 - 3 - 4 = z - 2z + z

0 = 0 (Infinitely many solutions)

5(a + 4) - 15 = -5(a - 1)

5a + 20 - 15 = -5a + 5

5a + 5a = 5 - 20 + 15

10a = 40

10a/10 = 40

a = 4

(one solution)

-2d + 4d - 4 = 5 + 3(d - 3)

2d - 4 = 5 + 3d - 9

2d - 3d = 5 - 9 + 4

- d = 0

d = 0

(one solution)

-11(n - 2) + 8(n + 1) = -3(n + 10)

-11n + 22 + 8n + 8 = -3n - 30

-11n + 8n + 3n = -30 - 22 - 8

0 = -60

(no solutions)

3x^2+48=0, solve the equation
MAXImum [283]

Answer:

16 + x2 = 0     (16)

I THINK

Step-by-step explanation: Simplifying

3x2 + 48 = 0

Reorder the terms:

48 + 3x2 = 0

Solving

48 + 3x2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-48' to each side of the equation.

48 + -48 + 3x2 = 0 + -48

Combine like terms: 48 + -48 = 0

0 + 3x2 = 0 + -48

3x2 = 0 + -48

Combine like terms: 0 + -48 = -48

3x2 = -48

Divide each side by '3'.

x2 = -16

Simplifying

x2 = -16

Reorder the terms:

16 + x2 = -16 + 16

Combine like terms: -16 + 16 = 0

16 + x2 = 0

The solution to this equation could not be determined.

The triangles are similar. If DE = 24, EF = 42, and AB = 8, find BC
Alik [6]
If triangle abc is similar to def
That means all angles are the same and sides will be multiplied by some factor x. So AB(x)= DE
8x=24
Therefore x =3
Now BC=EF/x
BC=42/3
BC= 14
