Solve for x: 2(x + 3)2 − 4 = 0
asambeis [7]

Answer:

Option D) x = −4.41, −1.59

Step-by-step explanation:

We are given the following expression in the question:

2(x + 3)^2 - 4 = 0

Solving the above expression, we get:

2(x + 3)^2 - 4 = 0\\2(x^2+9+6x)-4=0\\\text{Identity: }(a+b)^2 = a^2 + b^2 + 2ab\\2x^2+18+12x-4=0\\2x^2+12x+14=0\\\text{Using the quadratic formula:}\\ax^2 + bx +_ c = 0\\\\x = \displaystyle\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\text{Puting a = 2, b = 12, c = 14}\\\\x = \displaystyle\frac{-12\pm \sqrt{(12)^2-4(2)(14)}}{2(2)}\\\\x = \frac{-12 \pm 5.65}{4}\\\\x = \frac{-12 + 5.65}{4}, \frac{-12-5.65}{4} = -1.5875, -4.4125 \approx -1.59, -4.14

the length of a rectangle is 3cm less than its width. The perimeter is 54 cm. What are the dimensions of the rectangle
solong [7]

Answer:

The dimensions of the rectangle:

length: 12cm

width: 15 cm

Step-by-step explanation:

The perimeter of a rectangle is:

perimeter = 2(length+width)

54 = 2(a+b)

a = b - 3

a = legth

b = width

then:

54 = 2((b-3)+b)

54/2 = b-3 + b

27 = 2b - 3

27 + 3 = 2b

30 = 2b

b = 30/2

b = 15

a = b-3

a = 15 - 3

a = 12

Check:

54 = 2(15+12)

54 = 2*27
