54x^2+208x-308=-2x-8
54x^2+208x-308+2x+8=0
54x^2+210x-300=0
9x^2+35x-50=0 (divided both sides by 6)
9x^2+45x-10x-50=0 (wrote the 35x as a difference)
9x(x+5)-10(x+5)=0
(9x-10)(x+5)=0
Now solve the equations:
9x-10=0
x=10/9
x+5=0
x=-5

Therefore, x has two solutions, 10/9 and -5!!

Jacob is tiling his square walk with square tiles. He is able to fit 5 tiles up and 5 tiles across. If each tile has a length of

frozen [14]

Answer:

The perimeter of the kitchen wall = 60 b

Step-by-step explanation:

The number if tiles used in the length side of the square walk = 5 tiles

The length of 1 tiles = 3 b

So, the length of 5 tiles = 5 x ( Length of 1 tile)

= 5 x (3 b) = 15 b

So, the length of the square walk = 1 5 b

Perimeter of SQUARE = 4 x SIDES

⇒ Perimeter of the wall = 4 x (Side)

= 4 x (15 b) = 60 b

Hence, the perimeter of the kitchen wall = 60 b

If p varies directly with T and p =105 when T=400.Find p when T =500

kumpel [21]

Answer:

Step-by-step explanation:

The variation p varies directly with T is written as

p = kT

where k is the constant of proportionality

To find p when T =500 we must first find the formula for the variation

That's

when p = 105 and T = 400

105 = 400k

Divide both sides by 400

So the formula for the variation is

when

T = 500

Substitute it into the above formula

That's

$p = \frac{21}{80} \times 500$

Simplify

The final answer is

Hope this helps you
