When you have to divide by a fraction, you have to multiply the other number by the fraction's reciprocal.
8 = 3/4 w Divide by 3/4
w = 8/(3/4)
w = 8/ (3/4) = 8 x 4/3 Multiply by the numerator and divide by the denominator.
w = (8 x 4) / 3
w = 32 / 3
w = 10 2/3
Answer:
14 inches
Step-by-step explanation:
Perimeter of a rectangle
= 2(l + w)
Given length L = 3 inches and
Width w = 4 inches
Perimeter = 2(3 + 4)
Simplify the bracket
2 x 7
14 inches
Answer:

Step-by-step explanation:
Hello, the Conjugate Roots Theorem states that if a complex number is a zero of real polynomial its conjugate is a zero too. It means that (x-4i)(x+4i) are factors of f(x).

The coefficient of the leading term is 1 and the constant term is -240 = 16 * (-15), so we a re looking for a real number such that.

We identify the coefficients for the like terms, it comes
a = -2 and 16a = -32 (which is equivalent). So, we can write in
.

The sum of the zeroes is 2=5-3 and their product is -15=-3*5, so we can factorise by (x-5)(x+3), which gives.

And we can write in 

Hope this helps.
Do not hesitate if you need further explanation.
Thank you
You will get the same answers but with more zeros. For example 7x20 is 140, and 7x2000 is 14,000 but with more zero's
