Answer:

$\boxed{ \boxed{ \bold{ \sf{d = 15}}}}$

Step-by-step explanation:

$\sf{d - 7 = 8}$

Move constant to right hand side and change it's sign

⇒ $\sf{d = 8 + 7}$

Add the numbers

⇒ $\sf{d = 15}$

Let's check:

When d = 15 , R.H.S = 15 - 7 = 8

And L.H.S = 8

Thus , R.H.S = L.H.S when d = 15.

Therefore d = 15 is the solution of the equation.

Hope I helped!

Step-by-step explanation:

First of all, we need to find 20 percent of 35000.

now we increase the bed cost by 20 percent.

35000 + 7000 = 42000

How do I factorise 2t^2 + 5t +2

alekssr [168]

$2t^2+5t+2\\\\a=2;\ b=5;\ c=2\\\\\Delta=b^2-4ac;\ if\ \Delta > 0\ then\ t_1=\frac{-b-\sqrt\Delta}{2a}\ and\ t_2=\frac{-b+\sqrt\Delta}{2a}\\\\\Delta=5^2-4\cdot2\cdot2=25-16=9;\ \sqrt\Delta=\sqrt9=3\\\\t_1=\frac{-5-3}{2\cdot2}=\frac{-8}{4}=-2;\ t_2=\frac{-5+3}{2\cdot2}=\frac{-2}{4}=-\frac{1}{2}\\\\2t^2+5t+2=2(x+2)(x+\frac{1}{2})$
