Which expression is equivalent to 2d^2-6/d^2+2d-48 / d-3/2d+16if no denominator equals zero?
Please help. On Pluto
Answers
Answer:
B; 4/d-6
Step-by-step explanation:
We want to perform a division here
Flipping the right hand side while changing the sign to multiplication, we have that;
(2d - 6)/ (d^2 + 2d -48) * (2d + 16)/d-3
= 2(d-3)/(d^2 + 2d - 48) * 2d + 16/d-3
= 2/(d^2 + 2d - 48) * 2d + 16/1
2/(d-6)(d + 8) * 2(d + 8)/1
= 2/d-6 * 2/1
= 4/d-6

The surface area for a rectangular prism is given by the formula SA = 2ab + 2bc + 2ac, where a, b, and c are the lengths of the prism. If the surface area of a rectangular prism with side c measuring 12 meters is 434 square meters and length of side a measuring the same length as side b, then what is the length of side a of the rectangular prism?
Answers
Answer:
We are given
We are also given and , which allows us to rewrite the equation as
(I substituted every "b" with "a" and every "c" with "9").
The solutions to this quadratic equation are -25 and 7. We discard -25 because a side with negative length would make no sense.
The required measure of side a of the rectangular prism is a = 9.3 meters.
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
SA = 2ab + 2bc + 2ac
434 = 2a² + 14a + 14a
434 = 2a² + 28a
2a² + 28a - 434 = 0
a² + 14a - 217 = 0
a² + 14a + 49 - 49 - 217 = 0
(a + 7)² = 266
a = 9.3 or a = -23.3
Since the negative measure of length can be neglected.
a = 9.3 = b
Thus, the required measure of side a of the rectangular prism is a = 9.3 meters.

x=9
5(9)=45
Answer:
x=9 y=45
Step-by-step explanation:
y=4x + 9.......(1)
y= 5x.........(2)
Substitute 5x for y in equation 1.
5x= 4x + 9
5x - 4x = 9 (Collect like terms 5 and 4 have x in common if +4 crossover it changes to -4)
x = 9
substitute 9 for x in equation 2.
y = 5(9)
y = 5 x 9(multiplication)

The sun’s mass is 1.998 * 10^30 kg. Saturn’d mass is 5.69 * 10^26 kg. How many times as great as the mass of Saturn is the mass of the sun? Show your work using scientific notation
Answers
Answer: The mass of the sun is 3.51 x 10^3 times greater.
Step-by-step explanation:
X= Mass of Sun/ Mass of Saturn
X= 1.998 x 10^30 / 5.69 x 10^26
1.998/ 5.69 = .351
10^30 / 10^26 = 10^4
You want to move the decimal a value so you would subtract 1 from 4
3.51 x 10^3
The mass of the Sun is 3.511 × 10³ (in scientific notation) times more than the mass of Saturn.
What is division?The division means the separation of something into different parts, sharing of something among different people, places, etc.
The sun’s mass is [tex]1.998 * 10^{30}[/tex] kg.
Saturn's mass is [tex]5.69 * 10^{26}[/tex] kg.
Let the mass of the Sun be X times more than the mass of the Saturn mass.
The equation that can be written as
1.998 × 10³⁰ = X × 5.69 × 10²⁶
On simplifying, the value f X will be
[tex]\rm X = \dfrac{1.998 * 10^{30}}{5.69*10^{26}}\\\\X = 3511.42 \\\\X = 3.511 * 10^3[/tex]
The mass of the Sun is 3.511 × 10³ (in scientific notation) times more than the mass of Saturn.

A rectangle has a length of (2x-7) and a width of (x+5) perimeter
Answers
Answer:
6x - 4
Step-by-step explanation:
Perimeter is equal to double the length plus double the width, and if you use this to find perimeter, you would get that the perimeter = 2(2x-7)+2(x+5), which simplifies to 4x - 14 + 2x + 10, which simplifies to 6x - 4. That means that the rectangle's perimeter is 6x-4.

Answer:
Assuming that the x2 is x squared, B
Step-by-step explanation:
(1)(1) + 5(1) - 6 = 1 + 5 - 6 = 6 - 6 = 0
(-6)(-6) + 5(-6) - 6 = 36 - 30 - 6 = 6 - 6 = 0
Answer:
B
Step-by-step explanation:
Let's solve using factoring.
x²+5x-6=0
5 is the sum of the numbers, while -6 is their product.
Think: which two numbers add up to 5, but when multiplied, equal -6?
Those numbers are -1 and 6.
Now factor the polynomial:
(x-1)(x+6)=0
split into parts:
(x-1)=0
x-1=0
x=1
(x+6)=0
x+6=0
x=-6
So B

1.5:4=9:(2y+5)

Answer:
y = 9.5
Step-by-step explanation:
Express the ratios in fractional form, that is
[tex]\frac{1.5}{4}[/tex] = [tex]\frac{9}{2y+5}[/tex] ( cross- multiply )
1.5(2y + 5) = 36 ( divide both sides by 1.5 )
2y + 5 = 24 ( subtract 5 from both sides )
2y = 19 ( divide both sides by 2 )
y = [tex]\frac{19}{2}[/tex] = 9.5
