Answer:

Step-by-step explanation:

ΔBCA ~ ΔECD ⇒ the corresponding sides are proportional.

$\frac{AC}{DC}$ = $\frac{AB}{DE}$

AC = 4 + 6 = 10 cm

$\frac{10}{6}$ = $\frac{x+5}{x}$ ⇔ 10x = 6(x + 5) ⇒ <em>x = 7.5 cm</em>

- 30m^2 - 10m + 30

distribute your negative 10, you will first get 30m, then - 30m^2.

next distribute the negative 5, you will get - 40m, then 30.

combine like terms, and make sure its in standard form, - 30m^2 - 10m + 30

Answer:

$\frac{2A}{h} = b$

Step-by-step explanation:

this can be done by simple manipulation .
in the given equation, A is the subject.
so, by the above statement you can understand the meaning of making something as a subject.

given equation: A = 1/2 bh

multiply both the sides by 2,

2A = bh

divide both the sides by h,

$\frac{2A}{h} = b$

so, the required form is : $\frac{2A}{h} = b$
