Answer:

<h2>B. 3xy − 4x</h2>

Step-by-step explanation:

step one:

Given the expression  13x(9y – 12) we are expected to expand the expression to obtain a similar expression given in the options

step two

we proceed by

= 13x(9y-12)\\\\=(117xy-156x)

step three

we proceed to both terms in the expression

bt a common factor which is 39

\frac{117xy}{39}-\frac{156x}{39}

3xy-4x

From our analysis, the option D matches the expression

erma4kov [3.2K]

Answer:

Let the sides be a and b

a^2 + b^2 = c^2 = 29^2 = 841

a^2 + (a + 1)^2 = 841

a^2 + a^2 + 2 a + 1 = 841

2 a^2 + 2 a = 840

a (a + 1) = 420

21 * 20 = 420     trial and error

So the sides are 20 and 21

20^2 + 21^2 = 29^2
