If triangle dgh is congruent to triangle def find the value of x

Rom4ik [11]

Answer:

x = 25

Step-by-step explanation:

$\triangle DGH\sim\triangle DEF... (given)$

$\frac{DG}{DE} =\frac{GH}{EF}$

$\frac{52}{91} =\frac{x+3}{2x-1}$

$\frac{4}{7} =\frac{x+3}{2x-1}$

4(2x - 1) = 7(x + 3)

8x - 4 = 7x + 21

8x - 7x = 21 + 4

x = 25

What number must you add to the polynomial below to complete the square?<br><br> x2 + 15x

Aleksandr-060686 [28]

Answer:

The number $\frac{225}{4}$ is added to the polynomial below to complete the square.

Step-by-step explanation:

Perfect square binomial:

A perfect square binomial is given by:

$(a + b)^2 = a^2 + 2ab + b^2$

In this question:

We have that:

$a^2 + 2ab + b^2 = x^2 + 15x + ?$

Since $a = x$ , we have that:

$2ab = 15x$

$2b = 15$

$b = \frac{15}{2}$

Completing the square:

The term that completes the square is $b^2$ . So

$b^2 = (\frac{15}{2})^2 = \frac{225}{4}$

The number $\frac{225}{4}$ is added to the polynomial below to complete the square.
