Find the square of the following without actual multpliation . 43

devlian [24]

I'll explain how I found it without actual multiplication,

${40}^{2} = 1600 \\ {3}^{2} = 9 \\ 2 \times 40 \times 3 = 240 \\$

So,

${43}^{2} = 1600 + 240 + 9 \\ = 1849$

Hope this will help....

For this problem, assume there are 5 grey females, 4 grey males, 2 white females, and 6 white males. As in the book, the biologi

Leni [432]

Answer:

The required probability is 0.04411

Step-by-step explanation:

The number of female grey mice = 5.

The number of males grey mice = 4.

The number of female white mice = 2.

The number of male white mice = 6.

The number of mice = 17.

The probability of first mice be male grey = $\frac{4}{17}$

The probability of second mice be male grey = $\frac{3}{16}$

The probability of two mice be male grey = $\frac{4}{17} *\frac{3}{16}$ = 0.04411

:( A=? B=? please help me

Helen [10]

a= 16x+16

b= 40x + 15

Step-by-step explanation:

We know that perimeter of a rectangle is

$2(l + b)$

So therefore

$2(8x + 3 + 5) = a$

$= > 16x+ 6 + 10 = a$

$= > 16x + 16 = a$

Answer= A) that is perimeter is 16x+16

We know that area of a rectangle is l×b

So therefore

$(8x + 3) \times 5$

$= 40x + 15$

Answer = b) that is area is 40x + 15
