which of the following is the correct factorization of the trinomial below -7x^2+5x+12
Answers
It’s always good to know the several ways to solve these problems, but one of the easiest and fastest would be the box method.
The box method involves you finding you a, b, and c values in a quadratic equation. It goes as follows, Ax^2+bx+c. When doing the box method, you multiply only your A and c. In this case -7*12 which gives you -84. Next you just find you b value (which is 5).
Now comes the trick part, you need to find the factors of -84 that ADD UP to equal 5. Therefore we just find the factors of 84 by listing them (find them for 84 then determine with the negative later). So we have 2, 42/ 3,28/ 4/21/ 6,14 / and 7,12. It becomes easier to find your factor, but 7 and 12 can equal to 5 in this condition due to 84 being negative, therefore one of the factors will be negative. By making 7 negative we can make 12+-7 equal to our b value of 5.
Now that we have the factors, we put them into fractions. We put them in the form that a would be on top and the factor would be on the bottom. Therefore a/(factor). In this case is would be -7/12 and -7/-7. With these fractions, we then simplify as much as we can, -7/12 cannot be simplified so it stays the same, but -7/-7 can be simplified to 1/1.
These fractions then become you FACTORS of your quadratic equation, in which case the a value in the fraction adds x to it, therefore it would be -7x+12 and x+1. The correct would would be (-7x+12)(x+1).

Pizza by the Pan sold 4 dozen pizzas in the afternoon. That night, they sold 2.5 times as many pizzas as they did during the afternoon. How many pizzas did they sell in all that day?
Answers
Answer:
they sold 14 pizzas all day.
Step-by-step explanation:
4 x 2 = 8
0.5 means half of what they sold in the afternoon
4 ÷ 2 = 2
now add them both together to get the number of pizzas they sold at night.
8 + 2 = 10
now add the afternoon and night together
10 + 4 = 14
answer: 14 pizzas

An airplane flies 56 miles due north and then 33 miles due east. How many miles is the
plane from its starting point?
Answers
Answer:
65 miles
Step-by-step explanation:
using the Pythagorean theorem:
56²+ 33² = d²
d² = 4225
d = 65 miles
The distance of the plane from the starting point will be 65 miles. Distance or the displacement in the given case is found by the phythogorous theorem.
What is the distance?Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
An airplane flies 56 miles due north and then 33 miles due east.
The distance can be found with the help of the phythogorous theorem. The following calculation is done.
[tex]\rm AB^2+BC^2=AC^2 \\\\\rm (56)^2+(33)^2=AC^2 \\\\AC=65 \ miles[/tex]
Hence the distance of the plane from the starting point will be 65 miles.

1. The cross section of an A-frame cottage is an isosceles triangle. If the
slope of one of the sides is 1.8 and it is 19 feet high at the peak, what angle
does the side make with the horizontal? What is the width of the cottage?
Answers
Answer:
21.12
Step-by-step explanation:
To solve this, it's best to use Cartesian planes. So we draw it in the Cartesian planes. From the question, we have {0, 19} and also {1.8, 0}.
If x = -1.8 and x = +1.8, then
1.8 = (19 - 0) / (0 - x)
1.8 = 19 / -x
x = -19 / 1.8
x = -10.56
Since we're having it in 2 quadrants then, we have 10.56 + 10.56 = 21.12 to be our width of the cottage

A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches. 2 triangular sides have a base of 10 inches and height of 5.6 inches. 2 triangular sides have a base of 5 inches and height of 7.1 inches.
Answers
Answer:
Answer:
a) The base of the rectangular pyramid shown has an area of
60 square inches
b) A triangular face with a base of 10 inches has an area of 28 square inches.
c) A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) The total surface area of the pyramid is 151.5 square inches.
Step-by-step explanation:
a) Solving for question a, we were given the following parameters
A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches
The formula used to calculate the rectangular base of a rectangular pyramid =
Length × Width
Where :
Length = 10 inches
Width = 6 inches
Rectangular base = 10 inches × 6 inches
= 60 inches²
Hence, the base of the rectangular pyramid shown has an area of 60 square inches
b) Solving for question b, we have the following values given:
2 triangular sides have a base of 10 inches and height of 5.6 inches.
First step would be to solve for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (10 inches × 5.6 inches) ÷ 2
= 56inches² ÷ 2
= 28 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 28 inches².
A triangular face with a base of 10 inches has an area of 28 square inches.
c) Solving for question c, the following parameters are given:
2 triangular sides have a base of 5 inches and height of 7.1 inches.
We would be to solving for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (5 inches × 7.1 inches) ÷ 2
= 35.5 inches² ÷ 2
= 17.75 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 17.75 inches².
A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) Solving for d, it is important to note that, a rectangular pyramid has 5 faces and they are: The rectangular base and 4 triangular faces
The formula for the total surface area of the rectangular pyramid is given as
Total Surface Area of the rectangular pyramid = Rectangular Base + Area of Triangular Side A + Area of Triangular Side B + Area of Triangular Side C + Area of Triangular Side D + Area of Triangular Side E
Total Surface Area of the Rectangular Pyramid = 60 inches² + 28 inches² + 28 inches² + 17.75 inches² + 17.75 inches²
Total surface Area of the Rectangular pyramid = 151.5 inches²
The total surface area of the pyramid is 151.5 square inches.
