m_a_m_a [10]

It wants you to complete the function using -10 for x. . .

e.g: f(x) = 1/2x + 2

f(-10) = 1/2(-10) + 2
f(-10) = 3

Find the value of x that makes the two triangles equal

Leona [35]

Answer:

Step-by-step explanation:

$\triangle CDE \sim\triangle FGH...(given)$

$\therefore \frac{CD}{FG}=\frac{CE}{FH}...(csst)$

$\therefore \frac{4x}{28}=\frac{25}{35}$

$\therefore \frac{x}{7}=\frac{5}{7}$

$\therefore x=\frac{7\times 5}{7}$

$\therefore x=5$

What is the most logical first step in solving the equation x2 + 6x +9 = 10?

Shalnov [3]

Answer:

Step-by-step explanation:

The logical step is to <u>factorize the left side of the equation</u>, which becomes:

(x + 3)² = 10

Then, you can take the square root on both sides.

x + 3 = ±√10
x = ±√10 - 3

Not asked, but good to understand the procedure regardless.
