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
Answer: 60c
Step-by-step explanation: 3c times 20. This is the right answer I hope it helps <3
Answer:
=(x-3)(x+7)
Step-by-step explanation:
To factor the trimonial:
, we follow these steps:
Step 1: Multiply the first and last term

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

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.

The answer to the question
Answer
The correct answer is B
Step-by-step explanation:
It is B because squares don't intersect so it cant be a
They are always congruent and equal so not c or d it has to be B
