What are the solutions to the quadratic equation (5y + 6)2 = 24? y = startfraction negative 6 + 2 startroot 6 endroot over 5 endfraction and y = startfraction negative 6 minus 2 startroot 6 endroot over 5 endfraction y = startfraction negative 6 + 2 startroot 6 endroot over 5 endfraction and y = startfraction 6 minus 2 startroot 6 endroot over 5 endfraction y = startfraction negative 4 startroot 6 endroot over 5 endfraction and y = startfraction negative 8 startroot 6 endroot over 5 endfraction y = startfraction 4 startroot 6 endroot over 5 endfraction and y = startfraction 8 startroot 6 endroot over 5 endfraction

there are two solutions:

a) y =

b)

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

The solution is given in the image below

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
