The perimeter of a building is 78 feet. The width of the building is seven more than three times the length of the building. Wha

Alchen [17]

P=2l+2w

W=7+3l

So substitute into the original equation

P=2l + 2(7+3l)

78=2l +14 + 6l

-14 -14

—————-

64=8l

8=length

W=7+3l

= 7+3(8)

=7+24

=31

Check your work

Perimeter=8+8+31+31

=78

Hope this helps

slava [35]

Answer: $\frac{1}{3}\ s$

Step-by-step explanation:

Given

Distance traveled is $s=30t^2+440t$

for s=150 ft

$\Rightarrow 30t^2+440t=150$

$\Rightarrow 30t^2+440t-150=0\\\Rightarrow 3t^2+44t-15=0\\\Rightarrow (3t-1)(t+15)=0\\\Rightarrow t=\dfrac{1}{3}\ s$
