Find the area of rectangle ,semicircle and the figure​
ExtremeBDS [4]

Step-by-step explanation:

Srectangle=21*30=630cm^2

Ssemicircle=(11.5^2*pi)/2=132.25pi/2=66.125cm^2*pi

Sfigure=630cm*2+2*66.125cm^2*pi=630cm^2+pi*132.25pi

if we assume that pi=3.14

Sfigure=630cm^2+415.265cm^2=1045.265cm^2

Imagine you are teaching a younger student how to factor. Describe in full sentences what you would say to teach the young stude
djyliett [7]

Answer:

x^2+ 4x - 21 =(x-3)(x+7)

Step-by-step explanation:

To factor the trimonial: x^2+ 4x - 21, we follow these steps:

Step 1: Multiply the first and last term

-21 \times x^2=-21x^2

Step 2: List out product factors of the term derived above

-21=-1 \times 21\\ -21=-3 \times 7\\-21=3 \times -7\\-21=1 \times -21

Step 3: Determine which of the factors sum up to the middle term 4x

The required product is: -3 and 7

Therefore: -3x+7x=4x

Step 4: Replace the middle term by the expression derived in step 3 and factorize.

x^2+ 7x -3x- 21\\=x(x+7)-3(x+7)\\=(x-3)(x+7)
