Answer:
x=5
Step-by-step explanation:
Volume of a rectangular prism=b x l x h
Set up you equation
120=(4 x 12 x
)
Multiply inside the parentheses
120=(48x)
Multiply by
120=24x
Divide by 24 on both sides
5=x
Check you answer
Volume of a rectangular prism=b x l x h
Set up your equation
(12 x 5 x 4)
Multiply inside the parentheses
(240)
Multiply by
V=120yd³
(x-5)(4x+1)
4x^2 times -5 is -20 the factors of -20 are -1x20, 1x-20... but to make the -19x you would add together the 1 and -20 because 1-20 is -19.
This then splits off to factorise 4x^2-20x, making this side 4x(1x-5) carry the brackets over to make it 1(1x-5) joining the brackets together to make (4x+1)(x-5)
