Answer: 0

Step-by-step: you multiply 5 and 10 =50x then divide by 2 which is 25 and the you multiply that by 0 and 0 is your answer

Solve for x in the equation x squared 20 x 100 = 36. x = –16 or x = –4 x = –10 x = –8 x = 4 or x = 16

spin [16.1K]

Possible values of x is -4 or -16

<h3>How to solve?</h3>

${x}^2$ + 20x +100 = 36

$\\{x}^2$ + 20x + 100-36 = 0

$\\{x}^2$ + 20x + 64 = 0

Using middle term split

In this method splitting of middle term in to two factors, In Quadratic Factorization using Splitting of Middle Term which is x term is the sum of two factors and product equal to last term.

${x}^2$ + 4x + 16x + 64 = 0

x(x+4) + 16(x+4) = 0

taking common (x+4)

(x+4)(x+16) = 0

Either

x+4 = 0

⇒ x = -4

or (x+16) = 0

⇒ x = -16

Thus possible values of x is -4 or -16

If the basalt at the top of the ancient valley below Vulcan's Throne yields a radiometric date (K-Ar) of 15,000 years, and the l

zepelin [54]

Answer:

$1.69\times 10^3$ feet/million year

Step-by-step explanation:

We are given that

Elevation of top of basalt in valley =4100 feet

Elevation of bottom of basalt in valley =2100 feet

Age of top of basalt in valley=15000 years

Age of bottom of basalt in valley=1.2 million years= $1.2\times 10^6 years=1200000 years$

We have to find the rate of basalt filling in the valley in feet per million yeas

Rate of basalt filling in the valley= $\frac{Elevation\;of\;top\;of\;basalt\;in\;valley-elevation\;of\;bottom\;of\;basalt\;in\;valley}{age\;of\;bottom\;of\;basalt\;in\;valley-age\;of\;top\;of\;basalt\;in\;valley}$

Rate of basalt filling in the valley= $\frac{4100-2100}{1200000-15000}=\frac{2000}{1185000}=1.69\times 10^{-3} feet/year$

Rate of basalt filling in the valley= $1.69\times 10^{-3}\times 10^{6}=1.69\times 10^3$ feet/million year
