The length of a rectangular garden is 5 meters shorter than twice it width, the area of its region is 150 square meters. Find th

grin007 [14]

Step-by-step explanation:

length = x - 5

width = 2x

2x(x-5) = 150 m^2

2x^2 - 10x = 150 m^2

2x^2 - 10x - 150 = 0

(x=11.51 or x = -6.513)

if you wanna check,

2(11.51) × (11.51-5) = 150

23.02 × 6.51 = 150

149.8602 = 150

I'm not sure if its correct though^^

There was 4.35% error in Diego's measurements.

Step-by-step explanation:

Given,

Length measured by Diego = Approx value = 22 cm

Actual length = Exact value = 23 cm

Percent error = $\frac{|approx-exact|}{exact}*100$

$Percent\ error = \frac{|22-23|}{23}*100\\\\Percent\ error = \frac{|-1|}{23}*100\\\\Percent\ error = \frac{1}{23}*100\\\\Percent\ error = \frac{100}{23}\\\\Percent\ error = 4.347\%$

Rounding off to nearest hundredth

Percent error = 4.35%

There was 4.35% error in Diego's measurements.

Answer:

Step-by-step explanation:

Since the total degrees of ANY triangle is 180 degrees, start by subtracting 63 and 45 by 180.

180-63-45=72

Now take the 12 from (4x-12) and subtract that from 72.

72-12=60

Now divide 60 by 4 from the 4x.

60/4=15.
