The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417.

Step-by-step explanation:

From the question,

A store has 5 rings and 9 bracelets for sale. If all 14 items sell, the amount of money the store will take in can be determined by summing up the total cost of the rings and the total cost of the bracelets.

First, we will determine the total cost of the rings

From the question, a ring cost $125

∴ 5 rings will cost 5 × $125

5 × $125 = $625

Hence, the total cost of the rings is $625

For the bracelets

From the question, a bracelet cost $88

∴ 9 bracelets will cost 9 × $88

9 × $88 = $792

Hence, the total cost of the bracelets is $792

The amount the store will take in will be $625 + $792 = $1417

Hence, if all 14 items sell, the amount of money the store will take in will be $1417.

The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417

Answer from: Hrjohnson2004

The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417.

Step-by-step explanation:

From the question,

First, we will determine the total cost of the rings

From the question, a ring cost $125

∴ 5 rings will cost 5 × $125

5 × $125 = $625

Hence, the total cost of the rings is $625

For the bracelets

From the question, a bracelet cost $88

∴ 9 bracelets will cost 9 × $88

9 × $88 = $792

Hence, the total cost of the bracelets is $792

The amount the store will take in will be $625 + $792 = $1417

Hence, if all 14 items sell, the amount of money the store will take in will be $1417.

The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417

Answer from: Quest

x= -3 and $x=\frac{-3+/-3i\sqrt{3} }{2}$

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

$(x^3-a^3)=$ $(x-a)(x^2+ax+a^2)$

where a is the cube root of $a^3$ .

here this is 27 and the cube root of 27 is 3. so we write using the form:

$(x-3)(x^2+(3)x+3^2)\\(x-3)(x^2+3x+9)$ .

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$

where a = 1, b=3, and c=9

$x=\frac{-3+/-\sqrt{3^2-4(1)(9)} }{2(1)} \\x=\frac{-3+/-\sqrt{9-36)} }{2} \\x=\frac{-3+/-\sqrt{-27)} }{2}\\x=\frac{-3+/-3i\sqrt{3} }{2}$

this cubic has two complex roots.
