/5 /5
x=5

Use the difference of two squares to find the product of 22 and 18.

vladimir2022 [97]

Answer:

396

Step-by-step explanation:

Difference of two squares is breaking down numbers into pieces and using the distributive property to solve. The pieces should be in the form (a-b)(c+d).

Write 22 as (20 + 2) and 18 as (20-2).

(20+2)(20-2) = 400 + 40 - 40 - 4 = 400 - 4 = 396

The area of rectangular field is (49m2-42m+9).Find the dimensions of the field

Drupady [299]

Answer:

The dimensions are (7m-3) by (7m-3)

Step-by-step explanation:

We have the area of the rectangular field to be:

$49 {m}^{2} - 42m + 9$

We need to factorize this expression.

Let us rewrite to obtain:

${(7m)}^{2} - 2(7 \times 3)m + {3}^{2}$

We can easily see that the expression is actually a perfect square trinomial.

This gives us:

$(7m - 3)^{2}$

Or

$(7m - 3)(7m - 3)$
