since 2 sides will be 11 and the third side will be 8 the fourth side also needs to be 8 to make it a parallelogram

8 feet long. This is because a parallelogram has same side lengths on both opposite sides. If the first two are 11, the others are 8.

Find the area of the following ellipse (round to nearest tenth).
goblinko [34]

Answer:

\huge\boxed{A=60\pi cm^2}

Step-by-step explanation:

The formula of an area of a elipse:

A=\pi ab

We have:

2a=10cm\to a=5cm\\\\2b=24cm\to b=12cm

Substitute:

A=\pi\dot5\cdot12=60\pi(cm^2)

Solve the equation. x2 18x 81 = 25<br> a. 14, 4<br> b. –4, –14<br> c. 14, –14<br> d. –4, 4
Snowcat [4.5K]

Answer:

The answer is the option B

-4,-14

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

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

in this problem we have

x^{2}+18x+81=25  

x^{2}+18x+56=0  

so

a=1\\b=18\\c=56

substitute in the formula

x=\frac{-18(+/-)\sqrt{18^{2}-4(1)(56)}} {2(1)}

x=\frac{-18(+/-)\sqrt{100}} {2}

x=\frac{-18(+/-)10} {2}

x1=\frac{-18+10} {2}=-4

x2=\frac{-18-10} {2}=-14
