My natural tendency is to FIOL instead of FOIL but it doesn't matter.

(x+5)(x-6)

Firsts: x times x

Outers: x times -6 = -6x

Inners: 5 x

Lasts: 5(-6)=-30

Outers+Inners = -6x + 5x = -x

Answer: -x

(x-2)(x-3)=x^2-3x-2x+6=x^2-5x+6

Answer: second choice

Elza [17]

Answer:

Step-by-step explanation:

The length of the string attached with each balloon is equal to $12$ feet

In the party total number of balloon used is equal to $52$ balloons

The total length of the string required

Length of string used in one balloon * total number of balloons

$= 12 * 52 = 624$ feet

1 feet is equal to 13 yards

Total length of string required in yards $13 * 624 = 8112$ yards

Which function is equivalent to y = 3(x + 2)2 + 7 ?

Troyanec [42]

Step-by-step explanation:

Our function:

$y = 3(x + 2)^{2} + 7$

Include the exponent:

$y = 3(x^{2} + 4) + 7$

Use the Distributive Property:

$y = 3 {x}^{2} + 12 + 7$

Add:

$\boxed{y = 3 {x}^{2} + 19}$

tankabanditka [31]

Answer:

d) 0.0132

Step-by-step explanation:

In a sample of size n, with proportion p, the standard error of the proportion is:

$SE_{p} = \sqrt{\frac{p(1-p)}{n}}$

In this problem, we have that:

$p = 0.26, n = 1100$

$SE_{p} = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.26*0.74}{1100}} = 0.0132$

So the correct answer is:

d) 0.0132
