Answer:

No.

Step-by-step explanation:

(x+1)^2=(x+1)(x+1)=x^2+x+x+1=x^2+2x+1

This is different from x^2+1.

Thus, they are not equivalent.

Natalie has 48 tiles write a factor pair for the number 48

grandymaker [24]

A factor is a number multiplied by another factor to get a product:
a x b = c
a and b are factors and c is product.
So, for 48, factor pairs are:

1 x 48
2 x 24
3 x 16
4 x 12
6 x 8
8 x 6
12 x 4
16 x 3
24 x 2
48 x 1

(1+1/3)^2−2/9 I am about to have a mental breakdown, please somebody answer

Archy [21]

Answer:

$\frac{14}{9} = 1\frac{5}{9} \\\\1.5$

Step-by-step explanation:

$(1+1/3)^2-2/9\\\\= \left(1+\frac{1}{3}\right)^2-\frac{2}{9}\\\\\left(1+\frac{1}{3}\right)^2=\frac{4^2}{3^2}\\\\=\frac{4^2}{3^2}-\frac{2}{9}\\\\\frac{4^2}{3^2}=\frac{16}{9}\\\\=\frac{16}{9}-\frac{2}{9}\\\\\mathrm{Apply\:rule}\:\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}\\\\=\frac{16-2}{9}\\\\\mathrm{Subtract\:the\:numbers:}\:16-2=14\\=\frac{14}{9}$
