A. 2(3x-5)²

Step-by-step explanation:

18x² - 60x + 50

= 2 (9x² - 30x + 25 )  ⇒⇒⇒ take 2 as common from all terms

note: 9x² = 3x * 3x and 25 = 5*5 and

 3x * 5 *2 = 30x

so, this is a complete square

= 2(3x-5)(3x-5)

= 2(3x-5)²

Answer:

m = 5

a = -3

b = -15

Step-by-step explanation:

(m - 2) = 3 for x^2

(2a + 3) = - (m - 2) = (2 - m) for x^1

(b + 6) = (2a - 3) for x^0

Answer:

c. -8

Step-by-step explanation:

Given:

\frac{4b \div c}{1 - a}

a = 5, b = 8, and c = 1

To evaluate, plug in the values into the expression given.

Thus:

\frac{4(8) \div 1}{1 - 5}

\frac{32 \div 1}{1 - 5}

\frac{32}{-4}

\frac{8}{-1} = - 8

In scientific notation, 130,000,000 + 17,000,000 = ?
Illusion [34]

Answer: 1.47 * 10^8

Step-by-step explanation:

First, let's add in standard form to avoid confusion

130,000,000

+17,000,000

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

147,000,000

Since scientific notation expects the 1st base to be greater than 1 but less than 10, 147,000,000's first base in SCI notation should be 1.47.

Now to complete: 1.47 * 10^8

Hope this helps, please consider making me Brainliest.

You deposit $60 in an account earning simple interest at an annual rate of 5% after 12 years what is your new balance
Kaylis [27]

Answer:

The total amount accrued, principal plus interest, from simple interest on a principal of $60.00 at a rate of 5% per year for 12 years is $96.

Step-by-step explanation:

Given

Principle P = $60

Rate r = 5% = 5/100 = 0.05

Time period t = 12 years

To determine

New Balance A = ?

Using the formula

A = P(1 + rt)

A = 60(1+(0.05×12))

A = $96.00

Therefore, the total amount accrued, principal plus interest, from simple interest on a principal of $60.00 at a rate of 5% per year for 12 years is $96.
