Rewrite the function by completing the square. f ( x ) = 4 x 2 + 1 2 x + 9

x= 1.5

Step-by-step explanation:

4x2+12x+9=0

÷4   ÷4    ÷4    

Divide by 4  

4(x2+3x+2.25)=0

Factor

  (x+1.5)(x+1.5)

x+1.5=0

x=-1.5

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
