Let's solve this step-by-step. Here it is.

5x²+7x=x²+2

Step 1: subtract 2 from both the left and right side.

5x²+7x-2=x²+2-2

Simplify.

5x²+7x-2=x²

Step 2: subtract x² from each side.

5x²-x²+7x-2=x²-x²

Simplify.

4x²+7x-2=0

Step 3: solve using the quadratic formula.

[tex]x_{1,\:2}=\frac{-7\pm \sqrt{7^2-4\cdot \:4\left(-2\right)}}{2\cdot \:4}[/tex]

[tex]x_1=\frac{-7+9}{2\cdot \:4},\:x_2=\frac{-7-9}{2\cdot \:4}[/tex]

[tex]x=\frac{1}{4},\:x=-2[/tex]

Hope this helps!

Answer:

Measure of angle 4 is 115°

Step-by-step explanation:

First, we want to find the measure of angle 2, because the measure of angle 2 is equal to angle 4. When 2 straight lines cross each other, the angles formed are always equal to the angle right across from it.

Find angle 2 by setting up an equation:

[tex]x+x+50=180[/tex]

This is basically saying that angle 1 plus angle 2 equals 180°. In a half turnaround, the angle is 180°. Angle 1 and 2 make up a half turnaround.

Solve the equation:

[tex]x+x+50=180[/tex]

Combine the 2 x's to get 2x.

[tex]2x+50=180[/tex]

Subtract 50 from both sides.

[tex]2x=130[/tex]

Divide both sides by 2.

[tex]x=65[/tex]

Since x=65, plug 65 into x in the measure of angle 2 (x+50).

65+50=115.

Since Angle 2 is equal to angle 4, angle 4 is also 115.

Step-by-step explanation:

SinA=1/3=p/h

p=1,h=3,and b=?

Using Pythagoras Theorem,

b=√3^2-1^2

b=√9-1

b=√8=2√2

Now,

CosA=b/h=2√2/3

TanA=p/b=1/2√2

There is no phi in my keypad so I use A angle instead of phi.Adjust it.

Answer:

2 1/6 ft = 26 in

3 3/4 ft = 1 1/4 yrd

2 1/2 c = 1 1/4 p

3 2/3 yrs = 44 months

Step-by-step explanation:

Conversion:

ft to in = ft x 12

ft to yards = ft / 3

c to pints = c/2

yrs to months =  y x 12

Q. What do you mean by like terms and unlike terms?

⇢ Like terms are those which have the same base whereas unlike terms are those which have the different base [ For eg : In 6p , 3r , 4p & 4r , 6p and 4p are like terms as they have the same base i.e p & 3r and 4r are like terms as they have the same base i.e r ] . Like terms can be added or subtracted as per the signs given and unlike terms are kept as they are. Only coefficient of like terms can be added or subtracted.

Answer:

A ≈ 81.487 in²

Step-by-step explanation:

You know that circumference is C = 2πr, where r is the radius.

So,

C = 2πr

32 = 2(3.14)r

r ≈ 5.093 in

We also know that the formula for the area of a circle is A = πr², so:

A = πr²

A = (3.14)(5.093)²

A ≈ 81.487 in²

Out of 12 students to enroll should you expect to be graduate students would be 6 students.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

A university class has had 8 graduate students enroll so far, as well as 8 other students.

The total number of students = 16

Total graduate students = 8

So, out of 12 students to enroll should you expect to be graduate students

Given:

[tex]n(A)=12[/tex]

[tex]n(B)=7[/tex]

[tex]n(A\cup B)=10[/tex]

To find:

The value of [tex]n(A\cap B)[/tex].

Solution:

We know that,

[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]

After substituting the given values, we get

[tex]10=12+7-n(A\cap B)[/tex]

[tex]10+n(A\cap B)=19[/tex]

[tex]n(A\cap B)=19-10[/tex]

[tex]n(A\cap B)=9[/tex]

Therefore, the value of [tex]n(A\cap B)[/tex] is 9.

Note: The values are not correct because [tex]n(A)[/tex] cannot be greater than [tex]A\cup B[/tex]. The steps of solving these types of question are shown above.

Answer:

6

Step-by-step explanation:

geometric sequence is given as Tn=ar^n-1

where Tn is the last term,a is the first term, r is the common ratio, n is the nth term

hence 48=a2^(4-1)

48=a2^3

48=a8 (divide both by 8 to ramain with a)

6=a

therefore the first term is 6 .

Answer:

Step-by-step explanation:

look at picture

An equation to show that the plant grows 2 inches more in the second week than in the first week is n = c + 2.

In this scenario and exercise, you are required to write a linear equation to model the plant's growth in the second week with respect to the first week.

In order to write a linear equation to describe this situation, we would assign variables to the height of the plant in the first week and the height of the plant in the first week respectively, and then translate the word problem into an algebraic equation (linear equations) as follows:

Since the plant grew c inches in the first week, a linear equation to describe the height of the plant in the second week is given by;

n = c + 2

Answer: [tex]78^{\circ}, 102^{\circ}[/tex]

Step-by-step explanation:

Given

An angle measure [tex]24^{\circ}[/tex] more than its supplementary angle

Let the first angle be [tex]x[/tex]

So, another angle is [tex]x+24^{\circ}[/tex]

Also, the sum of the supplementary angles is [tex]180^{\circ}[/tex]

[tex]\therefore x+x+24^{\circ}=180^{\circ}\\\Rightarrow 2x=180^{\circ}-24^{\circ}\\\Rightarrow 2x=156^{\circ}\\\Rightarrow x=78^{\circ}[/tex]

So, the angles are [tex]78^{\circ}, 102^{\circ}[/tex]
