How do you know where to put the parentheses in an equation?

ziro4ka [17]

Parentheses are used to identify which numbers you should add,multiply .ect first. So If i had

12-(3+1)=x

then you would want to solve 3+1 before you subtract 12.

AB=11-4=7

$\\ \rm\hookrightarrow \dfrac{BC}{AB}=\dfrac{CE}{ET}$

ET be x

$\\ \rm\hookrightarrow \dfrac{4}{7}=\dfrac{8}{x}$

$\\ \rm\hookrightarrow 4x=56$

Triangle A″B″C″ is formed by a reflection over x = −1 and dilation by a scale factor of 4 from the origin. Which equation shows

juin [17]

Answer:

$\frac{AB}{A''B''} = \frac{1}{4}$

Step-by-step explanation:

Given the information:

A'B'C' reflection over x = −1
dilation by a scale factor of 4 from the origin

<=> the two triangles are similar to each other, triangles are similar if they have the same shape, but can be different sizes, so A″B″C″ is 4 time bigger than ABC

=> the relationship between ΔABC and ΔA″B″C″

= $\frac{AB}{A''B''} = \frac{1}{4}$

We choose C.

Hope it will find you well.
