B^2 + 8b + 16 factoring polynomials with a leading coefficient

Mathematics
1 answer:
Tomtit [17]3 years ago
3 0

Answer:

  (b +4)²

Step-by-step explanation:

Here, you recognize the constant as the square of half the coefficient of the linear term: 16 = (8/2)². This means the trinomial is a perfect square, so can be factored accordingly.

  b² +8b +16 = (b +4)²

Josiah traveled 79.5 miles on 3 gallons of gasoline. At this rate, how many gallons of gasoline would he need to travel 265 mile
BigorU [14]
Josiah would need 10 gallons to travel 265 miles.

First we divide 79.5 by 3 to find out how many gallons are needed for one mile.

79.5/3=26.5

For one mile we need 26.5 gallons of gas.

Now we will divide 265 by 26.5 to find the answer to the problem.

265/26.5=10

Josiah will need 10 gallons of gas to travel 265 miles

The perimeter of the semicircle is 25.71 cm. Calculate the value of radius x. Take pi to be 3.142
yan [13]

Answer:

5 cm

Step-by-step explanation:

Perimeter of semicircle =  \frac{1}{2}  \times 2\pi \: x +2x\\ 25.71 = 3.14 2\times x+ 2x\\ 25.71 = 5.14 2 x\\ x =  \frac{25.71}{5.142}  \\ x = 5  \: cm

Help please ! it’s one of the multiple choices
sammy [17]

Answer:

Option C

Step-by-step explanation:

\boxed{Log \ \dfrac{a}{b}=log \ a - log \ b}\\\\\boxed{(log \ a)^b=b*log \ a}

\sf log_w \ \dfrac{(x^{2}-6)^4}{\sqrt[3]{x^2+8} }=log_w \ (x^2-6)^4 - log_w(x^2+8)^{\frac{1}{3}}

                       \sf = 4*log_w \ (x^2 -6) - \dfrac{1}{3}log_w \ (x^2 + 8)
