The height of the tree would be 30 ft.

Step-by-step explanation:

This is because the smaller triangle would be 6/12 and the bigger triangle would be x/60. When you cross multiply these you find that x is 30.

vlada-n [284]

Answer: 55.4 mins

Step-by-step explanation:

pragnesh and qazi = 2hrs

pragnesh and roghui = 3hrs

qazi and roghui = 4hrs

this means for every 1 hour they wold paint.

pragnesh and qazi = \frac{1}{2} half of the fence

pragnesh and roghui = \frac{1}{3}

qazi and roghui = \frac{1}{4} quarter of the fence

time taken when they all work together

= \frac{1}{2} + \frac{1}{3} + \frac{1}{4}

= \frac{13}{12}

= \frac{12}{13}

= 0.9231 × 60(mins)

= 55.4 mins

Factorise completely 2y^2-4y
Serga [27]
To factor an expression, first you have to find the GCF or Greatest Common Factor of all of the pieces of the expression.

The GCF of 2y^2 and -4y is 2y

So, to factor this expression, we need to divide all of the pieces of the expression by the GCF.

2y(y-2)

2y^2 - 4y in completely factored form is 2y(y-2)
