The width of a rectangle is 15inches more than the length the perimeter is 90inches find the

Step-by-step explanation:

we have W=L+15 and P=90 lets replace W with this equation

P=2L+2W=2L+2(L+15)=2L+2L+30=4L+30

90=4L+30

60=4L

where L=60/4=15

we have W=30, L=15

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
