Answer:

1.x=10 and x=−2.

2. the answer is x=7,-1

3.=3, =1

Step-by-step explanation:

1.Since it is a quadratic equation, then it has, at the most, two solutions because the square root of the variable has a positive and negative value. Thus, the solutions to the given equation are x=10 and x=−2.

2.Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula. the you would simplify the equation.and the last thing that is to separate the equation.

Step-by-step explanation:

2.5x+12=32

We move all terms to the left:

2.5x+12-(32)=0

We add all the numbers together, and all the variables

2.5x-20=0

We move all terms containing x to the left, all other terms to the right

2.5x=20

x=20/2.5

x=8

The value of x for the expression is,

⇒ x = 8

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Expression is,

⇒ 2.5x + 12 = 32

Now, We can solve for x as;

⇒ 2.5x + 12 = 32

Subtract 12 both side,

⇒ 2.5x + 12 - 12 = 32 - 12

⇒ 2.5x = 20

Divide by 2.5 both side,

⇒ x = 20 / 2.5

⇒ x = 200 / 25

⇒ x = 8

Thus, The value of x for the expression is,

⇒ x = 8

Answer:

5

Step-by-step explanation:

Answer:

I am pretty sure the answer would be 6p+3

Step-by-step explanation:

I got this by solving (6 multplied by p) +3

You have to multiply 6 by p which will give you 6p

Than, you just add the +3 to the equation

This together would give you

(6*p) +3 = 6p+3.

Hopefully this answered your question!

Answer:

It would be 9 units.

Step-by-step explanation:

So to find the distance between two points, first start at one of the points then see how much distance there is between it and 0.

So taking 7 to start with, you would need to walk 7 units to get to 0.

However, we still need to get the distance till -2. So, we need to walk another 2 steps back, so it would be 9 units of walking in total.

Answer: [tex]3.675\ in.[/tex]

Step-by-step explanation:

Given

Wood shrinks 5% over the period of time

The width of the gap is 3.5 inch

The length of the rectangular block is 5 inch

So, the builder cut the rectangular block 5% bigger to compensate for the shrinkage

Required length is

[tex]\Rightarrow 3.5+5\%\times 3.5\\\Rightarrow 3.5+0.05\times 3.5\\\Rightarrow 3.5[1+0.05]\\\Rightarrow 3.675\ in.[/tex]

This is because, two sides are equal and one angle is equal.

And also there is one angle between 2 sides, so it’s SAS

Given:

Radius of the cylinder = 5 in

Height of the cylinder = 30 in.

To find:

The surface area of the cylinder.

Solution:

The surface area of the cylinder is:

[tex]SA=2\pi r^2+2\pi rh[/tex]

Where, r is the radius and h is the height of the cylinder.

Putting [tex]r=5,h=30,\pi=3.14[/tex] in the above formula, we get

[tex]SA=2(3.14)(5)^2+2(3.14)(5)(30)[/tex]

[tex]SA=2(3.14)(25)+942[/tex]

[tex]SA=157+942[/tex]

[tex]SA=1099 [/tex]

Therefore, the surface area of the cylinder is 1099  square inches.

Answer: (d)

Step-by-step explanation:

According to the triangle law of vector addition, the two vectors acting on a body are represented by the two sides of a triangle taken in order then the third side gives the resultant of the two vectors taken in the opposite order.

Here, option (d) aligns well with the triangle law of vector addition. The third side is in opposite order w.r.t the two vectors represented by the two sides of triangle i.e. [tex]3\vec{u}-2\vec{s}[/tex]

Answer:

29 degrees

Step-by-step explanation:

See attached image of an inscribed angle together with a central angle.

An inscribed angle is half the measure of the central angle!  Always!  In my image, if the measure of angle CAB is 58 degrees, then that is also the measure of arc CB.  The inscribed angle CDB is half the measure of the intercepted arc CB, so it's 29 degrees.

Answer:

The correct answer is 1/3.

Step-by-step explanation:

The reason why is because there is 3 animals. Then one beaver. So it would be 1/3.

Answer:

0.33

Step-by-step explanation:

Because they are all equal, each animal has to have the same percentage. Because there are 3 options it can land on, the denominator is 3. Because the beaver is 1 of the 3, the answer is 1/3. 1/3 is equal to 0.33 rounded so the answer is 0.33.

=========================================================

Explanation:

The independent variable is always long the horizontal axis. Often this is x, but we are using t in this case.

The variable t represents the amount of time in minutes. For instance, t = 2 means 2 minutes have elapsed. At this time, 4 cookies have been eaten as shown by the point (2,4). As another example, the point (3,6) means that d = 6 cookies have been eaten at time t = 3 minutes.

The equation is d = 2t because the '2' represents the rate of change of "eating 2 cookies per minute". Whatever the time value (t) is, we double it to get the value of d, which is the number of cookies eaten.
