In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x2 − 2xy + c is an algebraic expression.

5x−4x=3

Step 1: Simplify both sides of the equation.

5x−4x=3

5x+−4x=3

(5x+−4x)=3(Combine Like Terms)

x=3

Answer:

x=3

Which triangles are similar?

likoan [24]

Answer:

option B) ΔABE ∼ ΔADC

Step-by-step explanation:

The picture of the question in the attached figure

we know that

If two triangles are similar, then its corresponding sides are proportional and its corresponding angles are congruent

In this problem

Triangles ABE and ADC are similar by AA Similarity Theorem

because

m∠ ABE≅m∠ADC

m∠ BAE≅m∠DAC

The corresponding sides are

AB and AD

BE and DC

AE and AC

$\frac{AB}{AD}=\frac{BE}{DC}=\frac{AE}{AC}$
