Answer:

Step-by-step explanation:

Given

5 - $\sqrt{c+5}$ = 1 ( subtract 5 from both sides )

- $\sqrt{c+5}$ = - 4 ( multiply both sides by - 1 )

$\sqrt{c+5}$ = 4 ( square both sides )

c + 5 = 4² = 16 ( subtract 5 from both sides )

c = 11

What is the remainder when 19x^2 + 15x + 12 is divided by x - 2?

Aleksandr-060686 [28]

Answer:

R = 118

Step-by-step explanation:

Given

Represent the polynomial with P and the divisor with D

$P = 19x^2 + 15x + 12$

$D = x -2$

Required

Determine the remainder

We start by equating the divisor to 0

i.e.

$D = 0$

$x - 2 = 0$

$x = 2$

Substitute 2 for x in the polynomial.

This gives remainder (R)

$R = 19*2^2 + 15*2 + 12$

$R = 19*4 + 15*2 + 12$

$R = 76 + 30 + 12$

$R = 118$

<em>Hence, the remainder is 118</em>

What is the value of a?-2(a-8)+6a=36

saul85 [17]

$-2(a-8)+6a=36 \\ \\ -2a + 16 + 6a = 36 \\ \\ 4a + 16 = 36 \\ \\ 4a = 36 - 16 \\ \\ 4a = 20 \\ \\ a = \frac{20}{4} \\ \\ a = 5 \\ \\$

The final result is: a = 5.
