Blg is the answer to the question

the blue arc is showing that the angle of P & B are congruent, the single blue line shows that PF is congruent to BL

so in order for the triangles to be congruent the letters of the 2nd triangle need to be in the same order as the first

so P = B, F = L, and X = G

So answer would be BLG

If one side of a rectangle is five less than the other side and the perimeter is 90 inches, find the area of the rectangle.

horsena [70]

So given a rectangle
sides are
_x_
x-5|__|x-5
x

the perimeter is 90 inches
perimeter is
x + x + (x-5) + (x-5) = 90
combine like terms
2x + 2(x-5) = 90
distribute
2x + 2x-10 = 90
combine like terms
4x - 10 = 90
add 10 to both sides
4x= 100
divide both sides by 4
x = 25

now to find the length of a side
x is 25
and x-5 is 20

to check and see if that's right:
25 + 25 + 20 + 20 =?= 90
50 + 40 =?=
90 = 90

Now to find the area
A = b * h
so
x * (x-5)
substitute
25* 20
500
The area of the rectangle is 500

Hope this helps :)

What is 3.276 x 10^9 in standard form?

Delicious77 [7]

The exponent is a positive number, so you move the decimal point, that many places to the right:

3.276 x 10^9 = 3,276,000,000
