Which expression has a value that is equivalent to 5n+13 when n= -5

maks197457 [2]

Answer:

Option A is correct.

4n + 8 expression which has a value that is equivalent to 5n+13 when n = -5

Step-by-step explanation:

Given the expression: $5n + 13$

If n = -5

then, by substituting in given expression we get;

$5(-5)+13 = -25+13 = -12$

Option A:

4n + 8

Substitute the value of n = -5 we have;

$4(-5) + 8 = -20 + 8 = -12$

Option B:

2n + 2

then;

2(-5) + 2 = -10 + 2 = -8

Option C :

$n^2+13$

then;

$(-5)^2+13 = 25 + 13 = 38$

Option D:

n + 8

then;

-5 + 8 = 3

Therefore, only option A has expression which has a value that is equivalent to 5n+13 when n = -5

Surface area of a cylinder = $2\pi r^{2} + 2\pi rh$

r = 2m, h = 3m

$2\pi (2)^{2} + 2\pi (2)(3)$

= 62.83185

Okay can you please help me do this

sertanlavr [38]

Answer:

y=3

Step-by-step explanation:

Multiply 9 from both sides to cancel it out.

-27=-y/9

/9 /9

-3=-y

We can't have a negative variable, so we divide -1 from both sides.

-3=-y

/-1 /-1\

3=y
