Step-by-step explanation:

Perform the multiplication and addition:

$g(x)=-(x+4)^2-6=-(x^2+8x+16)-6=-x^2-8x-16-6\\\\g(x)=-x^2-8x-22$

<em>Comment on the squaring</em>

There are several ways you can find the square (x+4)².

Use your knowledge that (x+a)² = x²+2ax+a².
Use FOIL* to compute (x+4)(x+4) = x² +4x +4x +4² = x²+8x+16
Use the distributive property: (x+4)(x+4) = x(x+4) +4(x+4) = x² +4x +4x +4² (same as FOIL for two binomials)

* FOIL is mnemonic for {First, Outer, Inner, Last} referring to pairs of terms in the factors (x +a)(x +b). The x terms are the First terms. The Outer terms are the first x and b. The Inner terms are "a" and the second x. The Last terms are "a" and "b". You are to form the sum of those pairs of terms to find the product of the binomials.

Help with fractions of a whole number

Ymorist [56]

Answer:

22 tickets

Step-by-step explanation:

I assume you're asking about question 2

To find a fraction of a whole number you divide by the bottom number and multiply by the top number. If 2/3 are kids tickets then 1/3 are adult tickets so you divide by 3 and multiply by 1

$66 \div 3 = 22 \times 1 = 22$
