Answer:
The correct option is (C) 3 cm, 4 cm, 5 cm.
Step-by-step explanation:
Given that the rectangle is x²+4x-12, the possible sides will be given by:
a]
x²+4x-12
=x²+6x-2x-12
=x(x+6)-2(x+6)
=(x-2)(x+6)
thus the dimensions are (x-2) units (x+6) units
b]
x²+2xy-48y²
factorizing the above is:
x²+8xy-6xy-48y²
=x(x+8y)-6y(x+8y)
=(x+8y)(x-6y)
c]
24x²-4x-8
factoring the above we get:
=4(6x²-x-2)
=4(6x²+3x-4x-2)
=4(3x(x+2)-2(x+2))
=4(3x-2)(x+2)
=(12x-8)(4x+8)
Answer:
Step-by-step explanation:
8t = 10(1/2t) + 27
8(2t = 10(t) + 27
Number 4 is correct
Theres nothing to see on the screen
Let's plug in some numberz!!
And turn words into numberz.
Let x represent laps.
Let y represent total of laps.
Boys ran sixteen laps!!
Girls ran four more laps than boys.
Boys ran 16, so what's 16+4?
Correct, it's 20!!
Our equation is 0.25x = y.
Plug it in!!
What's 0.25 x 20?
Nailed it. It's 5!!
Hope this helped!
