S would be equal to 10. We’d multiply 45 by 2 to get the 90 then divide by 9 to isolate it

9s/2=45
9s=90 (Multiply both sides by 2)
s=10 (Divide by 9 on both sides)

Perform the indicated operation. (2a2 - 8)(4a4 + 16a2 + 64)

padilas [110]

We have the following expression:

$(2a^2 - 8)(4a^4 + 16a^2 + 64)$

So let's solve this problem step by step.

1st. Applying distributive property:

$(2a^2)(4a^4+16a^2+64)-8(4a^4+16a^2+64)$

2st. Applying distributive property again:

$8a^6+32a^4+128a^2-32a^4-128a^2-512$

3st. Grouping terms with the same base:

$8a^6+(32a^4-32a^4)+(128a^2-128a^2)-512$

4st. Solving, the result is:

$8a^6-512$

Help 50 points and brainlest only if you answer all the questions

klasskru [66]

Answer: See below

Step-by-step explanation:

a) 6(3x+4y-8)

Use the distributive property:

6*3x + 6*4y - 6*8

18x + 24y - 48

So D is the correct answer

b) Factor out 4 because it can fit into 12 - 3 times - and 4 - one time.

12+4x

= 4(3+x)

So D is the correct answer

c) When you expand both C and D and simplify, you get 16x+36 as solution

d) 14x+2y+10z

Factor out 2 because it can fit into 14, 7 times. 2, one time. And 10, 5 times

14x+2y+10z

= 2(7x+y+5z)

So D is the correct answer again ;)

What two numbers multiply to -126 and add up to -65

Airida [17]

Xy = -126
x + y = -65

$xy = -126$
$\frac{xy}{x} = \frac{-126}{x}$
$y = \frac{-126}{x}$

$x + y = -65$
$x + \frac{-126}{x} = -65$
$\frac{x^{2}}{x} + \frac{-126}{x} = -65$
$\frac{x^{2} - 126}{x} = -65$
$-65x = x^{2} - 126$
$0 = x^{2} + 65x - 126$
$x = \frac{-(65) \+ \sqrt{(65)^{2} - 4(1)(-126)}}{2(1)}$
$x = \frac{-65 \± \sqrt{4225 + 504}}{2}$
$x = \frac{-65 \± \sqrt{4729}}{2}$
$x = \frac{-65 \± 68.8}{2}$
$x = \frac{-65 + 68.8}{2}$ $or$ $x = \frac{-65 - 68.8}{2}$
$x = \frac{3.8}{2}$ $or$ $x = \frac{-133.8}{2}$
$x = 1.9$ $or$ $x = -66.9$

x + y = -65
  1.9 + y = -65
- 1.9   - 1.9
y = -66.9
  (x, y) = (1.9, -66.9)

or

  x + y = -65
  -66.9 + y = -65
+ 66.9 + 66.9
y = 1.9
  (x, y) = (-66.9, 1.9)

The two numbers that add up to -65 and can multiply to -126 are the numbers -66.9 and 1.9.
