Lets create both equations:

y + 2x = -1
y = x^2

therefore:

x^2 + 2x + 1 = 0
(x + 1)^2 = 0
x = -1
y = 1

Simply the expression given below (3x^3+4x^2+4x-12)+(-5x^3+9x^2-9x+20)

Svet_ta [14]

Answer:

1. Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)

A softball fits snuggly inside a cubical box that is 4 inches on each side. What is the volume of the softball that fits snuggly

Natali5045456 [20]

Answer:

33.5 cubic inches.

Step-by-step explanation:

If the softball fits perfectly inside the cubical box, the softball is a sphere with diameter of 4 inches (radius os 2 inches).

The volume of a sphere is given by:

$V= \frac{4}{3}\pi r^3$

For r = 2 inches:

$V= \frac{4}{3}*3.14* 2^3\\V=33.5\ in^3$

The volume of the softball is 33.5 cubic inches.

kiran and clare live 24 mile away from each other along a rail trail. One Saturday the two friends started walking toward each o

scZoUnD [109]

Answer:

$11:45\ am$

Step-by-step explanation:

Total distance between Kiran and Clare is 24 miles. They started walking at 8.00 am.

Speed of Kiran is 3 miles/hr and speed of Clare is 3.4 miles/hr.

So the relative speed of them is,

$=3+3.4=6.4$ miles/hr

Both the speed are added as they moving in opposite direction.

We know that,

$\text{Relative speed}=\dfrac{\text{Relative distance}}{\text{Time}}$

i.e $\text{Time}=\dfrac{\text{Relative distance}}{\text{Relative speed}}$

Putting the values,

$t=\dfrac{24}{6.4}=3.75\ hr=3\ hr\ 45\ min$

As they started at 8.00 am, so the time at which will meet will be,

$=8+3\ hr\ 45\ min=11:45$
