Answer:

6x^{2}+17x+7 and zeros are -7/3 and -1/2

Step-by-step explanation:

You multiply every property by every variable not in their own parentheses.

2x*3x=6x^2

2x*7=14x

3x*1=3x

7*1=7

6x^2+3x+14x+7

add like variables together 3x+14x

6x^2+17x+7

( To get the zeros just make each equation in the parentheses equal to zero and solve for x.) ex 2x+1=0   x=-1/2

Find the sum or difference. Write your answer in simplest form. 2 1/3 + 1 3/4
hammer [34]

Answer:

The Sum is 49/12 (improper), or 4 1/12 (mixed).

The Difference of these 2 fractions would be 2 1/3 - 1 3/4 instead of adding them. The answer is 7/12.

Step-by-step explanation:

I did it by converting the mixed fractions into improper fractions, then making the denominators the same, and adding them together.

dolphi86 [110]

Step-by-step explanation:

since the two angles are supplementary angles they add up to give 180°

therefore, 7x+2+3x-2=180°

or, 10x= 180°

or, x= 18°

A farmer plans to grow wheat and corn. Each acre of wheat requires 4 hours of labor and $20 of capital, and each acre of corn re
ElenaW [278]

Answer:

To maximize profits, the farmer should plant 120 acres of wheat, and no acre of corn.

Step-by-step explanation:

Given that a farmer plans to grow wheat and corn, and each acre of wheat requires 4 hours of labor and $ 20 of capital, and each acre of corn requires 16 hours of labor and $ 40 of capital, and the farmer has at most 800 hours of labor and $ 2400 of capital available, if the profit from an acre of wheat is $ 80 and from an acre of corn is $ 100, to determine how many acres of each crop should she plant to maximize her profit the following calculation must be performed:

Knowing that each acre of wheat has a 50% lower capital cost, 75% lower hours and a 20% lower profit, in principle this would be the crop to be planted to obtain better yields.

2400/20 = 120

120 x 4 = 480

120 x 80 = 9,600

Thus, to maximize profits, the farmer should plant 120 acres of wheat, and no acre of corn.

I need some help with this answer please.
Salsk061 [2.6K]

Answer:

The length of the base is \frac{3}{4}

Step-by-step explanation:

Since we know the formula to find the area of a triangle is A = \frac{1}{2} bh, we can plug in and solve for b. When we plug into the formula we get:

\frac{1}{2} (\frac{1}{5} )b = \frac{3}{40}

First multiply by 2 on both sides to get rid of the 1/2 on the left. After doing this we get:

\frac{1}{5}b = \frac{3}{20}

Then we can multiply by 5 on both sides to get rid of the 1/5 on the left. After doing this we get out answer:

b = \frac{3}{4}

The length of a football field is 120 yards from one and one to the other end zone.​
Andreyy89

Answer:

To solve, you need to use Pythagorean Theorum

a^2+b^2=c^2

100^2+53.33^2 = c^2

10,000+2844.0889=c^2

12844.1=c^2

square root

= 113 1/3 yards

So it is less than 120 yards

Step-by-step explanation:

Here's a primer on how the dimensions play out at every level, from high school football to the NCAA and on up to the NFL. There are two constants, across the level of competition: 120 yards (360 feet) of length and 53 1/3 yards (160 feet) of width.
