Answer:

It's 15

Step-by-step explanation:

perimeter is sum of all the sides

15+15+v = 45

30+v = 45

subtract 30 from both sides

v = 45-30

= 15mm

consider the point (x,y) lying on the graph of y=(x+3)^1/2. let L be the distance between the points (x,y) and (4,0). write l as

olga_2 [115]

$L=\sqrt{ (x-4)^2 + y^2 }$
and
$y=\sqrt{x+3} \Rightarrow x = y^2-3$

$L=\sqrt{ (x-4)^2 + y^2 }=\sqrt{ (y^2 - 3-4)^2 + y^2 }=\sqrt{ (y^2-7)^2 + y^2 }$

a car decreased in value from $980 to $720 in one year what was the per cent of decrease to the nearest whole per cent ?

kolezko [41]

The decrease was 27%.

Step-by-step explanation:

Old value = $980

New value = $720

Decrease = Old value - New value

$Decrease=980-720=\$260$

Percent decrease = $\frac{Decreased/ amount}{Old value}*100$

$Percent\ decrease=\frac{260}{980}*100\\Percent\ decrease=0.265*100\\Percent\ decrease= 26.5\%$

Rounding off to near whole percent

Percent decrease = 27%

The decrease was 27%.

Find the factored form of 4x3 – 8x2 – 12x

seraphim [82]

4 x³ - 8 x² - 12 x =
= 4 x ( x² - 2 x - 3 ) =
= 4 x ( x² - 3 x + x - 3 ) =
= 4 x ( x ( x - 3 ) + ( x - 3 ) ) =
= 4 x ( x - 3 ) ( x + 1 ) ( the factored form )
