The area of a rectangle is 99 ft^2, and the length of the rectangle is 7 more than double the width. Find the dimensions of the

Sergio039 [100]

Answer:

width =5.5ft

length =18

Step-by-step explanation:

w=x

L=2x+7

area=w*L

99 = x(2x+7)

$99=2x^{2} +7x$

$2x^{2} +7x-99=0$

$2x^{2} +18x-11x-99=0$

2x(x+9)-11(x+9)=0

(2x-11)(x+9)=0

2x-11=0

2x=11

x=11/2

x=5.5

L=2x+7=2*5.5+7=11+7=18

Find the volume of a sphere whose surface area is 1256 sq.cm (Take π = 3.14)<br>

Alekssandra [29.7K]

Curved surface area of a sphere =1256 cm

We know that, Curved surface area of a spehre =4πr

⟹1256=4×3.14×r

⟹r

4×3.14

1256

⟹r

=100

∴r=10 cm

Hence, the answer is 10 cm.

–4x – 7 = y x2 – 2x – 6 = y Which statement is true? There are no real number solutions. There is one unique real number solutio

Aleksandr [31]

Answer:

<h3>There is one unique real number solution at (–1, –3)</h3>

Step-by-step explanation:

Given the two linear equation

–4x – 7 = y ...1

x² – 2x – 6 = y ...2

Equating the left hand side of both equations since they are equal to the same variable y will give;

$-4x-7=x^{2} -2x-6\\collecting\ the\ like\ terms\\x^{2} -2x+4x-6+7 = 0\\x^{2} +2x+1 = 0\\x^{2} +x+x+1 = 0\\x(x+1)+1(x+1)=0\\(x+1)^{2}=0\\ taking\ square\ root\ of\ both\ sides\\x+1 = 0\\x = -1\\$

Substituting x=1 into equation 1 we have;

$y=-4(-1)-7\\y=4-7\\y = -3$

This means there is only one unique real number solution at (-1, -3)
