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)

monitta

Options:

a. Nikki's proposed placement will light a greater area than Dylan's placement.

b.  Dylan's proposed placement will light a greater area than Nikki's placement.

c.  Both proposed placements will light the same sized area.

d. Nikki's proposed placement will light more than half the yard.

e. Dylan's proposed placement will light more than half the yard.

f.  Dylan's proposed placement will light exactly half of the yard.

g. Nikki's proposed placement will light less than half of the yard.

Answer:

C) Both proposed placements will light the same sized area.

F) Dylan's proposed placement will light exactly half of the yard.

Step-by-step explanation:

The area of a triangle is (base x height) / 2, and both lights illuminate the same base and height = (60 x 38) / 2 = 1,140 sq ft

Both Dylan's and Nikki's proposed placement will lit exactly half of the yard. The yard's total area = 60 x 38 = 2,280 sq ft, which is twice the area lit by the lights.

Help please!<br> <br> Lines a and b are parallel.<br> <br> What is the measure of angle m?
AlexFokin [52]
So the transversal (line that crosses lines a and b) is 180 since its a straight line. given the angle degree 125, you can do 180-125 to get angle m.
