Answer:  3

Step-by-step explanation:

Let x be the missing base. In this case, base to the power of 2 means this number x times itself will equal 9.

9 = [tex]x^{2}[/tex]

[tex]\sqrt{9}[/tex] = [tex]\sqrt{x^{2} }[/tex]  [use square root to cancel the power of 2].

[tex]\sqrt{9}[/tex] = x

x = 3

Check: [tex]3^{2}[/tex] = 3 x 3 = 9

Answer:

P = 5x - 10

Step-by-step explanation:

The perimeter is:

P = L + w

L = 3x - 2

w = 2x - 8

P = 3x -2 + 2x - 8

P = 5x - 10

To know the exact value we need to know the value of x or the solve of one of the expressions above.

The product of the slopes of this line and the line perpendicular to it is equal to -1.

Note that the slope if the coefficient of x.

Let

[tex] \alpha [/tex]

be the slope of the given line.

Let

[tex] \beta [/tex]

be the slope of the line perpendicular to it.

I can therefore say,

[tex] \alpha \times \beta = - 1[/tex]

[tex] \frac{ - 4}{3} \times \beta = - 1[/tex]

[tex] \beta = \frac{ - 1}{ \frac{ - 4}{3} } [/tex]

[tex] \beta = \frac{ - 3}{ - 4} = \frac{3}{ 4} [/tex]

The slope is 3/4

Answer:

60

Step-by-step explanation:

A man purchase 5 dozen banana , find equation to find total number of banana and how many banana he have.

Total number of banana = 12 x 6

Total number of banana = 60

Total amount after 4 years will be $63. If he invest principle amount of $42 for rate of interest of 12.5%.

Simply multiply the principal amount by the interest rate and the time to calculate simple interest. "Simple Interest = Principal x Interest Rate x Time," the formula says. You must multiply the borrowed principal amount by 1 plus the interest rate.

The simple interest rate is the rate at which you borrow or lend money. When a borrower borrows money from a lender, the lender receives an additional sum of money. The principal is the borrowed money that is given for a specific period of time. The interest is the extra amount paid back to the lender for using the money.

First, converting R percent to r a decimal

r = R/100 = 12.5%/100 = 0.125 per year.

To find the total amount  A = P (1+rt).

= 42(1 + 0.125 *6)

=  $63

The total amount is $63

Step-by-step explanation:

i just took the test on edge.

The factor of the polynomial [tex]f(x) = 6x^4 - 21x^3 - 4x^2 + 24x - 35[/tex] is (a) 2x - 7

The polynomial function is given as:

[tex]f(x) = 6x^4 - 21x^3 - 4x^2 + 24x - 35[/tex]

To determine if 2x - 7 is a factor, we start by setting it to 0

[tex]2x - 7 = 0[/tex]

Add 7 to both sides

[tex]2x = 7[/tex]

Divide both sides by 2

[tex]x =3.5[/tex]

Substitute 3.5 for x in f(x)

[tex]f(3.5) = 6(3.5)^4 - 21(3.5)^3 - 4(3.5)^2 + 24(3.5) - 35[/tex]

[tex]f(3.5) =0[/tex]

Because f(3.5) equals 0, then 2x - 7 is a factor of the polynomial

  25.5 ft² = 1/2(7 ft +3.2 ft)h . . . . with the given numbers filled in

  (25.5/5.1) ft = h = 5 ft . . . . . . . . . divide by the coefficient of h

The height of the trapezoid is 5 ft.

Answer:

since ABC and ADE are similar,they have equal areas.

(AC)^2/(AE)^2=area ABC/ADE

areaABC=ACE=1

so substitute it in the afformentioned equation

u will get,AC=AE

The length of side CA in triangle ABC is c * (a² + ab + ac) / (a * (a + b + c)).

To find the length of side CA in triangle ABC, we need to use the concept of similarity and corresponding sides. Let's denote the lengths of sides in each triangle:

Triangle ABC:

Length of side AB: a

Length of side BC: b

Length of side CA: c

Triangle ADE:

Length of side AD: x (corresponding to side AB in ABC)

Length of side DE: y (corresponding to side BC in ABC)

Length of side EA: z (corresponding to side CA in ABC)

Since triangles ABC and ADE are similar, their corresponding sides are in proportion:

AD/AB = DE/BC = EA/CA

We know that AD corresponds to AB, and DE corresponds to BC, so we can set up the following proportions:

x/a = y/b

Solving for y, we get:

y = (b * x) / a

Next, we can set up the proportion for EA/CA:

z/c = x/a

Solving for z, we get:

z = (c * x) / a

Now, we have expressions for y and z in terms of x, a, and b. Since the sum of the lengths of the sides of a triangle is always constant, we can write the equation:

x + y + z = a + b + c

Substituting the expressions for y and z:

x + (b * x) / a + (c * x) / a = a + b + c

To find the value of x, we can multiply the entire equation by a to eliminate the denominator:

a * x + b * x + c * x = a² + ab + ac

Combining the x terms:

x * (a + b + c) = a² + ab + ac

Dividing both sides by (a + b + c):

x = (a² + ab + ac) / (a + b + c)

Now that we have found the value of x, we can substitute it back into the expression for z:

z = (c * x) / a

z = (c * (a² + ab + ac) / (a + b + c)) / a

Simplifying:

z = c * (a² + ab + ac) / (a * (a + b + c))

Thus, we have found the length of side CA in triangle ABC:

#SPJ2

Answer:

Step-by-step explanation:

Consider what y values you are getting by letting x = 5 and then letting x = 6.

when x = 5 , y = 20

y = m*5

20 = m*5                      Divide by 5

20/5 = m/5                  

4 = m

when x = 6 y = 24

y = mx

24 = m*6                     Divide by 6

24/6 = m

m = 4

So now we can be sure of our solution for x when y = 32

y = m*n

32 = 4*n                      Divide both sides by 4

32/4 = 4*n/4

n = 8

Answer: n = 8

Answer:

C. y = 1/8x

D. y = x - 133

Step-by-step explanation:

In order to find the answer, you have to think about the answer choices

A. is saying that if you multiply 152 by 8, you will get 19 which is definitely not true

B. is saying that y is equal to 152/133 which is not true since 152/133= 8/7 which is some wacky decimal

C. would make sense because if you divide 152 and 8, you will get 19

Which makes the equation true because if you multiply 1/8 by 152/1, you get 152/8 which simplifies to 19 which satisfies the equation

D. This would also make sense since 152-133=19

So at the end, we can come to a conclusion that:

C. and D. are the equations that satisfy the relation
