Hello!
To find the area of a rectangle you do length * width
You can plug in the values you know
(x - 2) * 5 = 30
Divide both sides by 5
x - 2 = 6
Add 2 to both sides
x = 8
The answer is 8
Hope this helps!
40! / 30! = 40*39*38*37*36*35*34*33*32*31
dividing this by 10! 10*9*8*7*6*5*4*3*2*1
= 4*13*19*37*17*11*4*31
= 847,660,528
5x-10=3x+40
5x=3x+50
2x=50
x=25
5*25=125
125-10=115
angle AEB=115
Hope this helps :)
Put the first number on top then start adding 6+0, 8+1, 0+4, 1+1, 0+0 and the answer is 69420
The answer is b to be sure
