Solve x^2 +14x=15 by completing the square

ivanzaharov [21]

Answer:

x = -15 and x = 1

Step-by-step explanation:

Since we have to use the complete the square method, we first need to rewrite the equation in the form $x^{2}+2ax+a^{2}=(x+a)^{2}$ .

This results in $x^{2} + 14x + 7^{2} = 15 + 7^{2}$ .

Next, we simplify the equation to get $x^{2} +14x+7^{2} = 64$ .

Factoring the left side gives us $(x+7)^{2} = 64$ .

Finally we solve the equations: $x+7=\sqrt{64}$ and $x+7=-\sqrt{64}$ .

This gives us x=1, and x=-15

Whats the volume of the pyramid shown

adell [148]

Answer:

Volume of the Pyramid = 40 cubic centimeters

Step-by-step explanation:

The volume of a pyramid is given by the formula:

$V=\frac{lwh}{3}$

Where

l is the length

w is the width

h is the height

In the figure shown, the length is 5, width is 4, and height is 6 (in cm). We just substitute and find the answer. Shown below:

$V=\frac{lwh}{3}\\V=\frac{5*4*6}{3}\\V=40$

So, we can say:

Volume of the Pyramid = 40 cubic centimeters
