Step-by-step explanation:

Given : AD=4 cm,DB=(x−4) cm,AE=8 cm and EC=(3x−19) cm.  

To Find : x

We know that, by BPT(Basic proportionality theorem)

DBAD=ECAE 

 

(x−4)4=(3x−19)8

4(3x−19)=8(x−4) 

12x−76=8x−32

 

Solving, we get x=11 cm

How would you find the answer to -200 + 14?
Oliga [24]

Answer:

-186

Step-by-step explanation:

When you add a positive number to a negative, it gets bigger (In value) . For example:

-5 + 4 = -1

-10 + 12 = 2

So for this equation, -200 + 14, all you have to do is subtract 14 from 200, which will get you 186.

Since you removed the negative, add it back to get -186

Igoryamba

Hello from MrBillDoesMath!

Answer:

(x + 6) (2 x - 9)

Discussion:

6 and -9 are the factors of the constant term as 6 * (-9) = -54

The x term is given by  -9x + 12x  = 3x   (multiply the factorization out)

Is -2t^2+3t+4 in standard form
Paul [167]

Answer:

-2t^2+3t+4 or -2t^2+3t^1+4t^0

Step-by-step explanation:

The equation is already written in standard form.

You write the largest exponents to the left and the smallest to the right.

<u>Your expression: </u>-2t^2+3t+4<u> can also be expressed as this below:</u>

-2t^2+3t^1+4t^0

t to the first power means mutiplying by t

t to the 0 power mean mutiplying by 1 or basically you get the same result

If t was 2...

3t= 3(2)=6\\3t^1=3(2)^1=3(2)=6

Same result:

4=4\\4t^0=4(2)^0=4(1)=4\\

How do u graph this ?
Tatiana [17]
Like this: https://www.desmos.com/calculator/oox8hpz76r

Replace each inequality with an equal sign and graph the corresponding line. Since those inequality symbols do not include the "or equal to" case, graph the line as a dashed line. Then, shade the half of the plane corresponding to the values of x and y that satisfy the inequality. Here, the coefficient of y is positive on the "greater than" side of the inequality, so the plane will be shaded for larger y-values, those above the line in each case.
