You invested $27,200 and started a business selling vases. Supplies cost $11 per

AleksAgata [21]

1,600 vases must be produced and sold to break even.

x($28-$11)=$27,200
Simplify to 17x=27,200
Divide 17x by 17 so it cancels out.
What you do to one side of the equation you have to do to the other.
27,200/17=1,600
x=1,600

Select the correct answer.

Svetlanka [38]

Answer:

<h3> $\boxed{ \boxed{ \bold{ {x}^{2} + 4x - 21}}}$ </h3>

Step-by-step explanation:

$\sf{(x - 3)(x + 7)}$

Use the distributive property to multiply each term of the first binomial by each term of the second binomial.

⇒ $\sf{x(x + 7) - 3(x + 7)}$

⇒ $\sf{ {x}^{2} + 7x - 3x - 21}$

Collect like terms

⇒ $\sf{ {x}^{2} + 4x - 21}$

Hope I helped!

Best regards!!

Points E, F, and D are located on circle C. Circle C is shown. Line segments E C and D F are radii. Lines are drawn from points

elena55 [62]

Answer:

Option (1). 34°

Step-by-step explanation:

From the figure attached, CE and CD are the radii of the circle C.

Central angle CED formed by the intercepted arc DE = 68°

Since measure of an arc = central angle formed by the intercepted arc

Therefore, m∠CED = 68°

Since m∠EFD = $\frac{1}{2}(m\angle ECD)$ [Central angle of an intercepted arc measure the double of the inscribed angle by the same arc]

Therefore, m∠EFD = $\frac{1}{2}(68)$

= 34°

Therefore, Option (1) 34° will be the answer.
