What is surface area of a cuboid?

The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.

Given that, Yolanda makes wooden boxes for a crafts fair.

The dimensions of box are length= 5 inches, breadth = 3 inches and height = 2 inches.

We know that, the formula to find the toral surface area of cuboid is 2(lb+bh+hl)

Now, surface area = 2(5×3+3×2+2×5)

= 2(15+6+10)

= 2(31

= 62 square inches.

Therefore, the surface area of one box is 62 square inches.

Use a vertical format to subtract the polynomials.
3x2 - 2x + 2
- (7x2 + 2x - 3)

Answers

Answer:

Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]

Step-by-step explanation:

We need to u se a vertical format to subtract the polynomials.

The polynomials given are:

[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)[/tex]

Now, solving

For, subtraction, the sign of the terms [tex]7x^2 + 2x - 3[/tex] will be changed. - will convert to + because (-)(-) = + and positive sign will be converted to negative (-)(+) = -

The sign with the resulting term will be the sign of term that has greater coefficient. For example if we are subtracting 3x^2 and (-7x^2), the result will be -4x^2 because 7 has negative sign. (term has greater coefficient)

[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)\\\\:\:\:\:\:\:\:-\:\:\:\:-\:\:\:\:\:+\\-----------\\-4x^2-4x+5[/tex]

Answers

Answer:

First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).

Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

chicken tenders or chicken nuggets

Answers

Answer:

i dont know which one to choose but chicken tenders

Answer:

Chicken tenders.

Step-by-step explanation:

Chicken nuggets are the gross consumption of organs including lungs and others mushed together and fried. In return kids run to it because (most) kids only eat gross stuff. This made the marketing campaign SKY ROCKET with kids everywhere trying to get a bite. FORCING their poor parents to get them that disgusting mush. And then dip it in ketchup. Which is NOT a fruit or veggie. (As the school system thinks they are a veggie.)

While chicken tenders are chopped off the chicken meat then rolled in bread crumbs. And then deep fried to make a crispy exterior with a delicious tender interior.  Without getting mushed together with other things.

Also you never know what they put in that chicken nugget since its mushed together ‍♀️.
