Answer:
Step-by-step explanation:
<u>Pool:</u>
Width = x ft
Length = (x+6) ft
<u>Pool along with walkway:</u>
Width = x + 5 + 5 = (x + 10) ft
Length = x + 6 + 5 + 5 = (x + 16) ft
Total area of the pool with walkway = 950 sq.ft
length * width = 950
(x+16) * (x + 10) = 950
Use FOIL method,
x*x + x *10 + 16*x + 16 *10 = 950
x² + 10x + 16x + 160 -950 = 0 {Add like terms}
x² + 26x - 790 = 0
Answer:
y=1/4x-1.5
Step-by-step explanation:
So, because the line is parallel, the slope is the same. Then, to get the y-int, you do b=y-mx with the point, so the equation is b=-1-(1/4)(2), then you multiply to get b=-1-(0.5), so your y-int is -1.5.

Answer:
Step-by-step explanation:
A.
P=(219/800)×(218/799)≈0.0747≈0.075
B.
800-219=581
P=(581/800)×(580/799)≈0.527
c.
P( 1 think role models and one thinks not role models)+P(both thinks they are role models)=(219/800)×(581/799)+(219/800)×(218/799)=(219×581+219×218)/(800×799)
=[219(581+218)]/(800×799)
=(219×799)/(800×799)
=219/800
=0.27375
=0.274
<u>3</u> x <u>5
</u><u />4 6
multiply the numerators (top numbers) = <u>15</u>
multiply the denominators (bottom numbers) = 24
you can reduce the fraction by dividing top and bottom of the fraction by 3
<u>15</u>÷3= <u>5</u>
24÷3= 8
