NemiM [27]3 years ago
7 0

Answer:

C

Step-by-step explanation:

look up rules of multiplying radicals.

You can multiply the radicands (the number inside the square root) then take the square root of the new number.

3*21 = 63

Factor 63 into 3*3*7

Pull out 3^2 from inside the square root

leaves you with 3sqrt7 or answer C

How can I solve ¾ - (-5/12)?
Oksana_A [137]

Answer:

1 \frac{1}{6}

Step-by-step explanation:

\frac{3}{4}+ \frac{5}{12} =?\\

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

(\frac{3}{4} × \frac{3}{3} ) + (\frac{5}{12} ×\frac{1}{1})=?

Complete the multiplication and the equation becomes

\frac{9}{12} + \frac{5}{12}

The two fractions now have like denominators so you can add the numerators.

\frac{9+5}{12} = \frac{14}{12}

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 14 and 12 using

GCF(14,12) = 2

14÷2 / 12÷2 =7/6

The fraction

7/6

is the same as

7÷6

Convert to a mixed number using

long division for 7 ÷ 6 = 1R1, so

7/6= 1 \frac{1}{6}

Therefore:

3/4 − (−5/12) = 1 \frac{1}{6}

Solution by Formulas

Apply the fractions formula for subtraction, to

3/4 − (−5/12)

and solve

(3×12) − (−5×4) 4×12

=3/6− (−20/48)

=56/48

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF( 56,48) = 8

56÷8 / 48÷8 =7/6

Convert to a mixed number using

long division for 7 ÷ 6 = 1R1, so

7/6= 1 \frac{1}{6}

Therefore:

3/4 − (-5/12) = 1 \frac{1}{6}

Find the domain of the function f(x) = 7x2 + 8x - 15.
amm1812

Answer:

Domain is all real numbers or (negative infinity, positive infinity)

Step-by-step explanation:

Domain is all values of <em>x</em> (inputs) that will work with the function. Since a parabola has no limits for <em>x</em>, and all numbers work for <em>x</em>, then the domain can be any number. That leaves us with All Real Numbers as our answer.
