4 (a+3)=36 show all steps

PtichkaEL [24]

$4(a+3)=36$
Delete the parentheses, multiplying with the number of outside, making the set of signals
$4a + 12 = 36$

Number with incognito are to the left of the equality and numbers without incognito are to the right, remembering that when changing of side changes the signal.

$4a = 36 - 12$
$4a = 24$
$a = \frac{24}{4}$
$\boxed{a = 6}$

Confirm that the solution is correct:
$4(a+3)=36$
$4(6+3)=36$
$4(9)=36$
$36=36$ (TRUE)

Answer:
$\boxed{a = 6}$

triangle DEF a dilation of triangle ABC by scale 1/3 Which of the following proportions verifies that triangle ABC and triangle

11Alexandr11 [23.1K]

Answer:

Correct option: B -> AB/DE = AC/DF

Step-by-step explanation:

To verify that the triangles are similar, the proportion of two sides in a triangle needs to be the same proportion of the matching sides in the other triangle. The matching sides are:

AB and DE, AC and DF, BC and EF.

So we would have that:

AB/AC = DE/DF -> AB/DE = AC/DF

AB/BC = DE/EF -> AB/DE = BC/EF

AC/BC = DF/EF -> AC/DF = BC/EF

So the correct option is B -> AB/DE = AC/DF
