|x2+x-20<br> 22-11x+28<br> e:<br> x2-x-30<br> 3x-18
elena-s [515]

Answer:

x2 - 10x - 1994

Step-by-step explanation:

Step  1  :

Trying to factor by splitting the middle term

1.1     Factoring  x2-10x-1994

The first term is,  x2  its coefficient is  1 .

The middle term is,  -10x  its coefficient is  -10 .

The last term, "the constant", is  -1994

Step-1 : Multiply the coefficient of the first term by the constant   1 • -1994 = -1994

Step-2 : Find two factors of  -1994  whose sum equals the coefficient of the middle term, which is   -10 .

     -1994    +    1    =    -1993

     -997    +    2    =    -995

     -2    +    997    =    995

     -1    +    1994    =    1993

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 x2 - 10x - 1994

The radius of a circle is 9 times the radius of a smaller circle. The area of the smaller circle is 50 square centimeters. What
scoundrel [369]

Answer:

Let R = radius of big circle

r=radius of small circle

A1=Area of small circle

A2=Area of big circle

R=9r

A1=50cm^2

A1=pi*r*2

A2=pi*R^2

A2=pi*(9r)^2

A2=81*pi*r^2

A2=81*A1

A2=4050cm^2

Hence the big circle has area of 4050cm^2

Can someone help on a construction of a tangent to a circle please, need pictures if possible
Anit [1.1K]

Wassup

Steps:

1. Draw a line connecting the point to the center of the rectangle

2. Then construct a perpendicular bisector to the line drawn in step 1

3. Place the compass on the midpoint of the line, adjust its length to reach the end point, and draw an arc across the circle

4. Where the arc crosses the circle will be the tangent points. So connect the endpoint to the tangent point

Hope the picture helps you too

the spoke of a wheel reaches from the center of the wheel to its rim. If the circumstances of the rim of the wheel is 42 inches,
jekas [21]
The spoke of the wheel serves as the radius of the circle. 
To solve for the circumference of the circle, we use this formula:

C = 2πr
42 inches = 2 * 3.14 * r
42 inches = 6.28 * r
42 inches / 6.28 = r 
6.69 inches = r

The length of each spoke is 6.69 inches.
