could some please help me with this?

Answer:

Step-by-step explanation:

a₁ = 37

a₂ = 74

Common difference d = a₂ - a₁ = 37

nth term = a₁ + (n-1)d

= 37 + (n-1)37

= 37n

Answer:

Below in bold.

Step-by-step explanation:

The common difference is 74-37 = 37.

nth term a(n) = a1 + (n - 1)d

= 37 + 37(n - 1)

= 37n.

Hope this helped!

Answer:

[tex](10x + 9 {)}^{2} [/tex]

Step-by-step explanation:

1) Rewrite it in the form a² + 2ab + b², where a = 10x and b = 9.

[tex](10x) ^{2} + 2(10x)(9) + {9}^{2} [/tex]

2) Use square sum: ( a + b )² = a² + 2ab + b².

[tex](10x + 9 {)}^{2} [/tex]

Hence, the answer is (10x + 9)².

Answer:

-9

Step-by-step explanation:

(x + 89)° + (x + 109)° = 180°

(interior angles on the same side of transversal)

(2x + 198)° = 180°

2x + 198 = 180

2x = 180 - 198

2x = - 18

x = - 18/2

x = - 9

Step-by-step explanation:

The equation is y = -3x + 6.

Answer:

3y = 5x + 15

Step-by-step explanation:

Slope = Change in y-cordinates

---------------------------------

Change in x-cordinates

= 0 - (-5)/-3 - (-6)

= 5/3

Using point (-3,0)

y - y1 = m(x - x1)

y - 0 = 5/3 (x - (-3))

y = 5/3 (x + 3)

Expand the bracket

y = 5x/3 + 15/3

Multiply through by 3

3y = 5x + 15

Answer:

Step-by-step explanation:

Simplify the following:

1/(4^(11/3)×4^(-2/3))

Hint: | Simplify radicals.

1/4^(2/3) = 1/(4^2)^(1/3) = 1/(2^4)^(1/3) = (1/2^(1/3))/2:

1/(4^(11/3)×(1/2^(1/3))/2)

Hint: | Multiply numerator and denominator of 1/(2 2^(1/3)) by 2^(2/3).

Rationalize the denominator. 1/(2 2^(1/3)) = 1/(2 2^(1/3))×(2^(2/3))/(2^(2/3)) = (2^(2/3))/(2×2):

1/(4^(11/3)×(2^(2/3))/(2×2))

Hint: | Multiply 2 and 2 together.

2×2 = 4:

1/(4^(11/3)×(2^(2/3))/4)

Hint: | Separate the exponent of 4^(-11/3) into integer and fractional parts.

4^(-11/3) = 4^(1/3 - 12/3) = 4^(-12/3)×4^(1/3):

(4^(-12/3) 4^(1/3))/((2^(2/3))/4)

Hint: | Divide 12 by 3.

12/3 = (3 (-4))/3 = 4:

(4^(-4) 4^(1/3))/((2^(2/3))/4)

Hint: | Compute 4^4 by repeated squaring.

4^4 = (4^2)^2:

(4^(1/3))/((2^(2/3))/4) 1/(4^2)^2

Hint: | Evaluate 4^2.

4^2 = 16:

(4^(1/3))/(16^2×(2^(2/3))/4)

Hint: | Evaluate 16^2.

| 1 | 6

× | 1 | 6

| 9 | 6

1 | 6 | 0

2 | 5 | 6:

(4^(1/3))/(256×(2^(2/3))/4)

Hint: | Simplify radicals.

4^(1/3) = (2^2)^(1/3):

1/(256×(2^(2/3))/4) 2^(2/3)

Hint: | Write (2^(2/3))/(256×(2^(2/3))/4) as a single fraction.

Multiply the numerator by the reciprocal of the denominator, (2^(2/3))/(256×(2^(2/3))/4) = (2^(2/3))/256×4/2^(2/3):

(2^(2/3)×4)/(256×2^(2/3))

Hint: | Cancel common terms in the numerator and denominator of (2^(2/3)×4)/(256×2^(2/3)).

(2^(2/3)×4)/(256×2^(2/3)) = (2^(2/3))/(2^(2/3))×4/256 = 4/256:

4/256

Hint: | Reduce 4/256 to lowest terms. Start by finding the GCD of 4 and 256.

The gcd of 4 and 256 is 4, so 4/256 = (4×1)/(4×64) = 4/4×1/64 = 1/64:

Answer: 1/64

Answer:

Step-by-step explanation:

19.87 = 100%

If you divide both sides by ten, you would get what ten percent is.

1.987 = 10%

Multiply this by two to get 20%.

3.974 = 20%

Minus twenty percent from the original amount.

18.87 minus 3.974 = 15.886 after the discount.

Answer:

5310

Step-by-step explanation:

6% of 4500=270

270x3years=810

4500+810=5310

Lara will be paying the total amount is $5310

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Given that, Lara borrowed $4500 for some home repairs. She will be paying 6% in simple interest over the next three years.

We need to find the total amount she will be paying on the loan,

So, the formula for simple interest is - SI = PRT / 100

P = principal, r = rate and t = time

Therefore,

SI = 4500 x 6 x 3 / 100

= 45 x 18 = 810

The interest = $810

She will pay = interest + principal = 810 + 4500 = $5310

Hence, Lara will be paying the total amount is $5310

Apply zero product rule.

j = 0  or j-30 = 0

Find the value of j.
