Y = x2 + 12x + 30<br> 8x − y = 10
faltersainse [42]
So you need the solve for x and y ?

from 8x-y = 10,
y = 8x -10

Plug this in other equation.
8x-10 = x^2 +12x + 30

Re-arrange and combine like terms,
x^2 +12x -8x +30+10 = 0
x^2 +4x +40 = 0

This does not have any real solutions.
So there are no real values of x and y satisfying the 2 equations.

Are you sure the question is correct? or if this question belongs to complex numbers topic?

The end of a house has the shape of a square surmounted by an equilateral triangle. If the length of the base is measured to be
sergij07 [2.7K]

Answer:

The area of the end is 1755.44 ft²

Therefore, the maximum error in calculating area of the end is 8.3592

Step-by-step explanation:

Consider the provided information.

The length of the base is measured to be 35 feet, with a maximum error in measurement of 1 inch,

1\ inch = \frac{1}{12}\ feet

The area of shape = Area of square + Area of equilateral triangle

A=x^2+\frac{\sqrt{3}}{4}x^2

Substitute x=35 in above.

A=(35)^2+\frac{\sqrt{3}}{2}\times (35)^2=1755.44

Hence, the area of the end is 1755.44 ft²

Differentiate A=x^2(1+\frac{\sqrt{3}}{4}) with respect to x as shown:

dA=2x\ dx(1+\frac{\sqrt{3}}{4})

Substitute dx =1/12 and x=35

dA=2(35)\ \frac{1}{12}(1+\frac{\sqrt{3}}{4})=8.3592

Therefore, the maximum error in calculating area of the end is 8.3592
