I need help solving quadratics
jolli1 [7]

Quadratic equations are the equations that can be re arranged in the linear or the standard form.

<u>Explanation:</u>

In algebra, a quadratic equation is any condition that can be adjusted in standard structure as where x speaks to an unknown, and a, b, and c speak to known numbers, where a ≠ 0. On the off chance that a = 0, at that point the condition is straight, not quadratic, as there is no term.

Quadratic equations are really utilized in regular day to day existence, as while ascertaining regions, deciding an item's benefit or figuring the speed of an article. Quadratic conditions allude to conditions with in any event one squared variable, with the most standard structure being ax² + bx + c = 0.

A kitchen is 12 ft. by 14 ft. with 10 ft. high walls. How much would it cost to put vinyl flooring in this room? $8.80 per ft
Feliz [49]

<em>Answer:</em>

<em>In my opinion the answer would be 520x.</em>

<em>Step-by-step explanation:</em>

<em>Let x be the price of wallpaper per square feet. </em>

<em>Dimensions of a kitchen are: </em>

<em>width: w = 12 ft </em>

<em>length: l = 14 ft </em>

<em>height: h = 10 ft </em>

<em> </em>

<em>If you need to put wallpaper in the room, you will put it only on the walls. There are 4 walls in the kitchen: two walls which dimensions are 12 ft and 10 ft, and two walls which dimensions are 14 ft and 10 ft. Since walls are of rectangular shape, we will use the following formula for the area of walls: </em>

<em>A = 2 * w * h + 2 * l * h </em>

<em>A = 2 * 12 * 10 + 2 * 14 * 10 </em>

<em>A = 240 + 280 </em>

<em>A = 520 ft² </em>

<em> </em>

<em>So, if 1 square foot costs x, 520 square feet will cost </em><em><u>520x</u></em>

The Freeman family is barbecuing veggie burgers, corn cobs, and mushroom caps in their local park. If 3 8 of the items barbecued
slavikrds [6]

Answer:

The answer is below

Step-by-step explanation:

The Freeman family barbecued veggie burgers, corn cobs, and mushroom caps. 3/8 of the items barbecued are veggie burgers, and 1/3 of the items barbecued are corn cobs.

Let the total number of berbecued items be x. Therefore:

x = barbecued veggie burgers + barbecued corn cobs + barbecued mushroom caps

Barbecued veggie burgers = (3/8)x, barbecued corn cobs = (1/3)x, Let barbecued mushroom caps be y

Substituting:

x = (3/8)x + (1/3)x + y

Multiply through by 24

24x = 9x + 8x + 24y

24x = 17x + 24y

24y = 24x - 17x

24y = 7x

y = (7/24)x

barbecued mushroom caps = (7/24) of items

7/24 of the items barbecued are mushroom caps
