Answer:

your answer is 5.

Step-by-step explanation:

all the sides are the same because of the right angle signs; that means the lines are 90 degrees and are midway markers in this triangle. for example, the midway markers mean EC is 3 as well, and BEC is 6, since 3+3=6.

so since we know ge is 4, and we know be is 3, we know ad = be and dg = eg. find the hypotenuse of these two bad boys. a^2+b^2=c^2.

now plug in variables: 3^2+4^2=ag^2. 9+16=25. find the square root of the hypotenuse (because we need ag, not ag^2). your answer is five, and you're done. :)

Factor -7x^3+21x^2+3x-9 by grouping. what is the resulting expression?

Daniel [21]

Answer:

c) (3-7x^2)(x-3)

Step-by-step explanation:

-7x^3+21x^2+3x-9

Factor out a -7x^2 from the first two terms and a 3 from the last two terms

-7x^2 (x -3) +3(x-3)

Now factor out (x-3)

(x-3) (-7x^2+3)

Rearranging)

(x-3) (3-7x^2)

Answer:

$m = \dfrac{3}{4}$

Step-by-step explanation:

We would like to find the slope of the line of the given equation .

$\longrightarrow y =\dfrac{3}{4}x -1$

We know that slope intercept form of the line is given by ,

$\longrightarrow y = mx + c$

where ,

m is the slope
c is y intercept

Now we can compare the given equation with the slope intercept form to find the slope . You will see that 3/4 is present at the place of m .Therefore ,

$\longrightarrow \underline{\underline{m=\dfrac{3}{4}}}$
