2, 20, 36, 50 is a prefect square

The answer is B 16,4,1

:>

Answer:

A = f(1), which is the first term of the sequence, so there's no need for a formula to find A. When finding B, we can use the formula f(n) = f(n − 1) + B. n =

Answer:

w=−98

Step-by-step explanation:

Simplify both sides of the equation.

252=154−w

252=154+−w

252=−w+154

Step 2: Flip the equation.

−w+154=252

Step 3: Subtract 154 from both sides.

−w+154−154=252−154

−w=98

Step 4: Divide both sides by -1.

[tex]\frac{-w}{-1}=\frac{98}{-1}[/tex]

w=−98

Answer:

a) 169 = 13² = 84+85

b) 225 = 15² = 112+113

c) 289 = 17² = 144+ 145

d) 6561 = 81² =  3280+ 3281

Step-by-step explanation:

Explanation:-

a) Given  169 is an odd number

Squares of odd numbers, as a sum of two consecutive positive integers

169 = 13² = 84+85

b)

Given  225 is an odd number

Squares of odd numbers, as a sum of two consecutive positive integers

225 = 15² = 112+113

c)

Given  289 is an odd number

Squares of odd numbers, as a sum of two consecutive positive integers

289 = 17² = 144+ 145

d)

Given  6561 is an odd number

Squares of odd numbers, as a sum of two consecutive positive integers

6561 = 81² =  3280+ 3281

Answer:

n = -20

Step-by-step explanation:

(n + 7)2 = n - 6

2n + 14 = n - 6

14 = -n - 6

20 = -n

Checking my answer

(-20 + 7)2 = -20 - 6

(-13)2 = -26

-26 = -26

Answer:

A

Answer:

A) 21.6 units

Step-by-step explanation:

Use the distance formula for each length:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d=\sqrt{(-4-2)^2+(0-3)^2}\\d=\sqrt{36+9}\\d=\sqrt{45}\\\\ d=\sqrt{(2-4)^2+(3-0)^2}\\d=\sqrt{4+9}\\d=\sqrt{13}\\\\d=\sqrt{(4-0)^2+(0--4)^2}\\d=\sqrt{16+16}\\d=\sqrt{32}\\\\d=\sqrt{(0--4)^2+(-4-0)^2}\\d=\sqrt{16+16}\\d=\sqrt{32}\\\\p=\sqrt{45}+\sqrt{13}+\sqrt{32}+\sqrt{32}=21.62746371[/tex]

This means that option A is the closest answer

23-y=8 x=16

24-y=1.5 x=1.5

25-b=9 a=8

26-y=3.5 x= 3.5

that's what I know i don't think my answers are fully right

Answer:

x = 8

Step-by-step explanation:

small triangle is similar to larger one

set up a proportion:    9    =   x + 4

                                  9+12     x+4+2x

9  = x+ 4                    cross-multiply:  9(3x + 4) = 21(x + 4)

21     3x + 4                                            27x + 36 = 21x + 84

                                                              6x + 36 = 84

                                                               6x = 48

                                                               x = 8

Answer:

£3.25

Step-by-step explanation:

Hi there!

First, let’s add up how much they spent, which would be £56.75

If he paid with 3 £20 notes, he would have paid £60.

Now all we have to do is subtract 56.75 from 60, and we are left with

£3.25 in change.

Hope this helped!

Answer:

a(7) = -32.

Step-by-step explanation:

if a(x) = -5x+8

then a(7) = -5(7) + 8.

-5(7) +8

-40+8

-32.

Answer:=3a+2b−21

Step-by-step explanation:

Let's simplify step-by-step.

3a+2b−7−4−10

=3a+2b+−7+−4+−10

Combine Like Terms:

=3a+2b+−7+−4+−10

=(3a)+(2b)+(−7+−4+−10)

=3a+2b+−21

Answer:

question 13 = D

Step-by-step explanation:

because you do some math, open a calculator and boom, you have that.

Answer:

y=-3x-6

Step-by-step explanation:

Slope intercept form is y=mx+b

m is the slope  (in this problem that is -3)

b is the y-intercept  (in this problem that is -6)

Plug the slope and intercept you were given in and you get the equation of the line in slope intercept form

y=-3x-6
