Answer:

$x=17$

Step-by-step explanation:

$(6x+10)(x+17)(4x-34)$

$6x+10+x+17+4x-34=180$

Add:- $6x+x+4x=11x$

and $10+17-34=-7$

So, $11x-7=180$

Add 7 to both sides:-

$11x=187$

Divide both sides by 11:-

$\frac{11x}{11}=\frac{187}{11}$

$x=17$

Find the discriminant of the following quadratic equation then state the number of rational, irrational, and imaginary solutions

lianna [129]

Answer:

-6x² - 6 = -7x - 9
-6x² + 7x - 6 + 9 = 0
-6x² + 7x + 3 = 0
6x² - 7x - 3 = 0

<u>Discriminant:</u>

D = (-7)² - 4*6*(-3) = 49 + 72 = 121

<u>Since D > 0, there are 2 real solutions:</u>

x = (- (-7) ±√121 )/12
x = (7 ± 11)/12
x = 1.5, x = -1/3

cho tứ giác ABCD. Gọi M,N,P,Q là trung điểm của các cạnh AB, CD, AD, BC. Chứng minh rằng vecto MP = vecto QN, vecto MQ = vecto P

Dmitriy789 [7]

Answer:

Step-by-step explanation:

Xét tam giác DAB có: P là trung điểm AD, M là trung điểm AB

=> MP là đường trung bình của tam giác DAB => MP//BD và MP= $\frac{1}{2}$ BD (1)

Xét tam giác DBC có: N là trung điểm DC, Q là trung điểm BC

=> QN là đường trung bình của tam giác DBC => QN//BD và QN= $\frac{1}{2}$ BD (2)

Từ (1) và (2) => vecto MP song song cùng chiều với vecto QN

và độ dài MP = độ dài QN = $\frac{1}{2}$ BD

=> vecto MP = vecto QN

Tương tự xét các tam giác DAC và tam giác ABC => vecto MQ = vecto PN
