Solve the following quadratic equationx+12x+36 - 16

Mathematics

Answer:

x= -2, x= -10

Step-by-step explanation:

x^2 + 12x + 36 = 16

Began by setting this quadratic equation to 0. To do this, in this equation you must subtract.

x^2+12x+20=0

Next, we plug this into the quadratic formula, where a in this case is 1(there is nothing in front of x^2), b is equaled to 12(there is a 12 as the coeefficient of 12x), and c is equaled to 20.

The quadratic formula is as goes:

(-b+-(this means plus or minus)√b^2-4ac)/(2a)

After pluggin in and simplifying, the answer is x= -2 and x= -10

PLEASE HELP WITH THIS LAST QUESTION!!!!!

In-s [12.5K]

I was trying to figure it out but all i got was the meaning of the upside down U. so in the theory of a 9th grader i think...

you would have to distribute A' in to ( C U B)

because with the information i got it has to be in all so by distributing it would be in "all".

being a 9th grader i don't know if this helped but i hope it did just a little! and i deeply apologize if it doesn't.

Find the missing value for log4 9- log4 11= log 4 [ ]

Alexandra [31]

Answer:

Step-by-step explanation:

Hi there,

To get started, recall the logarithm rules. For this question, we can use the log rule specifically when subtracting two log functions that have the same base:

$log_b\alpha -log_b\beta =log_b[\frac{\alpha }{\beta } ]$

In this prompt, our base is 4, so b in the above formula. Using this formula, we can find the missing argument (the number inside of the log, what we are asked to solve for):

$log_49-log_411=log_4[\frac{9}{11} ]\\$ hence the missing argument is 9/11

At this point, there is no easier say to simplify, unless you wish to approximate 9/11 as 0.818. If you wish to solve for the exponent, you will have to use common log or natural log to do so.

If you liked this solution, leave a Thanks or give a rating!

thanks,

Length of the hypotenuse of the triangle to the nearest tenth of a metre

Lemur [1.5K]

Answer:

The length of the hypotenuse is 2.4m

Step-by-step explanation:

well to start we have to know the relationship between angles, legs and the hypotenuse

α = 55°

o: opposite = 2.0m

h: hypotenuse

sin α = o/h

cos α= a/h

tan α = o/a

we see that it has (angle, hypotenuse, opposite)

we look at which meets those data between the sine, cosine and tangent

is the sine

sin α = o/ah

Now we replace the values and solve

sin 55 = 2.0/h

0.81915 = 2.0/h

h = 2.0 / 0.81915

h = 2.4415 m

round to the nearest tenth

h = 2.4415 = 2.4 m

The length of the hypotenuse is 2.4m
