Multiply the side length by 3.
3(d+ 5)

Answer:

The tree was 33.6 meters tall.

Step-by-step explanation:

So the question is "How tall is the tree?" I take it.

tree height/shadow length = ladder height / shadow length

Notice that the heights are both in the numerator. A proportion should always do this. It should have the same units on either the two denominators or the 2 numerators.

x / 42 = 2.4 / 3                  Multiply both sides by 42

x = 42 * 2.4 / 3

x = 100.8 / 3

x = 33.6

Answer:

33.6

Step-by-step explanation:

x/42 = 2.4/3

x = 2.4/3 x 42

x = 2.4/1 x 14

x = 33.6/1

x = 33.6

Answer:   - 8.3c - 15

Step-by-step explanation:

(-2c + 5) + (-6.3c - 20)

-2c + 5 - 6.3c - 20

-2c - 6.3c - 20 + 5

- 8.3c - 15

Answer:

The answer is b

Answer:

12

Step-by-step explanation:

23=r+11

r=23-11

r=12

Answer:

r=12

Step-by-step explanation:

We are given the equation 23=r+11. To solve for r, one side of the equation needs to be r, so we will isolate r by subtracting 11 on both sides:

23-11=r+11-11

12=r

Because the +11 and -11 cancel out, we are left with r on the right side of the equation and 12 on the left side. Therefore, the value of r is 12, or r=12.

Step-by-step explanation:

i hope you understand

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Start by using the distributive property with 2(x+1) --> 2x+2

2. Your equation will be 2x + 5 = 3 + 2x + 2

3. Add the 3 and the two on the left side to be 5 + 2x

4. Your equation will be 2x + 5 = 5 + 2x

5. Now minus 2x from both sides so the 2x will cancel out

6. 5 = 5

Answer:

a₅₂ = - 212

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 8 and d = a₂ - a₁ = - 12 - (- 8) = - 12 + 8 = - 4 , then

a₅₂ = - 8 + (51 × - 4) = - 8 - 204 = - 212

Answer:

The two triangles are congruent because the squares in the corner state it's 90 degrees, and the two tick marks show they are also congruent. \

Answer:

Yes

Step-by-step explanation:

Yes

ASA Criterion for Congruence

ASA Criterion stands for Angle-Side-Angle Criterion. Under ASA criterion, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.

Here Angle Q and Angle S are 90  

and side QR = RS

and Angle QRP = Angle SRT (Vertically opposite angles)

By that we can prove these two triangles are congruent

Answer:

No. It's not rational because B is an Irrational number.

Answer:

D

Step-by-step explanation:

a - 3 = 7 ( add 3 to both sides )

a - 3 + 3 = 7 + 3 , that is

a = 10

It's B which would be -26

Answer:

z = 56

Step-by-step explanation:

z + 68 + z = 180

2z + 68 = 180

2z = 180 - 68

2z = 112

2z/2 = 112/2

z = 56

Step-by-step explanation:

since KJ and HI are parallel

z+68+z=180(cointerior angles sum up to 180)

2z+68=180

2z=180-68

2z=112

z=112/2

z=56

Answer:

  -1/5

Step-by-step explanation:

Divide by the coefficient of p/q:

  -25/5 × p/q / (-25/5) = 1 / (-25/5)

  p/q = -5/25

  p/q = -1/5 . . . . in reduced form

Step-by-step explanation:

False

If the positive number is greater than the negative, then it will stay positive.

say the question is 5+ -3.

The answer would be 2

Answer:

False

Step-by-step explanation:

It depends on what sign the larger number is. For example, -5+9= 4 because they are opposite signs and 9 is the larger number of the two, therefore the answer is a positive 4.

Answer:  $20.35

Step-by-step explanation: 16.75 * 0.15 = a 16.75 16.75 * 0.065 = b 16.75 + a + b

Step-by-step explanation:

2(x + 10) = 3x - 30

2x + 20 = 3x - 30

2x - 3x = -30 - 20

-x = -50

x = 50°

Answer:

-2n-3

Step-by-step explanation:

-5 , -7 they go up in steps of -2

but it was -2n this would be how it would go

a) -2 -4 -6 -8

which you can see is -3 off each time

so -2n which is a)  

and then -3

= -2n-3

plz say thanks ! xxx

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 1, 4 ] , then

f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36

f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then

average rate of change = [tex]\frac{-36-(-6)}{4-(-1)}[/tex] = [tex]\frac{-36+6}{4+1}[/tex] = [tex]\frac{-30}{5}[/tex] = - 6

Answer:

it's may be positive.

Answer:

$3,619.09

Step-by-step explanation:

liam deposits $2400 into an account that earns 8.3% interest compounded quarterly.

Compound interest formula is

where A is the final amount

P is the initial amount deposited

r is the rate of interest

n is the compounding period

t is the time in years

P= 2400, r= 8.3%= 0.083, t=5, n=4 (quarterly)

Plug in all the values

A= 3619.09
