Answer:

x=\frac{-3+-\sqrt{-7}}{2}

Step-by-step explanation:

Given equation is x^2+3x+4=0

Apply quadratic formula to solve for x

x=\frac{-b+-\sqrt{b^2-4ac}}{2a}

The value of a=1, b=3 and c=4

Plug in all the values and solve for x

x=\frac{-b+-\sqrt{b^2-4ac}}{2a}

x=\frac{-3+-\sqrt{3^2-4(1)(4)}}{2(1)}

x=\frac{-3+-\sqrt{9-16}}{2}

x=\frac{-3+-\sqrt{-7}}{2}

The square root is negative . so it is complex

The area of a rectangle is 44 square units. Its length measures 4 units. Find the length of its diagonal. Round to the nearest t
NikAS [45]

Answer:

√(137)

Step-by-step explanation:

First, you will need to find the other side length.....then you can use the Pythagorean Theorem to find the diagonal:

L x W = 44

4 x W = 44

W =11

Now the Pythag, Theorem:

 diagonal^2 = 4^2 + 11^2

        d^2 = 16+121

         d^2 = 137

          d = √(137)

The rectangular rug in Marcia's living room measures 12 feet by 109 inches. What is the rug's area in square feet?
Marrrta [24]

Answer:

109 square feet.

Step-by-step explanation:

109 in: = 109/12 = 9.0833333.... = 9 5/60 = (540+5)/60 = 545/60

Area = L*w

L = 545/60 feet

W = 12 feet

Area = 545/60 *  12

Area = 545*12/60

Area = 545 /5 = 109 square feet.

The area of the track will be 78501 m². The area of the track is equal to the area of the circle.

<h3>What is the area?</h3>

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square meters and other similar units are used to measure area.

The area of the track is found as;

\rm A=\frac{\pi}{4} d^2 \\\\ \rm A=\frac{3.14}{4} (100)^2 \\\\ A=7850 \ m^2

Hence, the area of the track will be 78501 m².

solniwko [45]

Answer:

x = 10

Step-by-step explanation:

We know that is a right angle which is 90 degrees.

we know one angle is 30 degrees.

So take 90- 30 = 60

now we solve for 6x

6*10 = 60 and 60+30=90

x = 10
