5+3x-2andx+2(x+1)+1=

Mathematics
1 answer:
Anuta_ua [19.1K]3 years ago
8 0

Step-by-step explanation:

5 - 3x - 2 = x + 2(x + 1)

Group like terms at the LHS and open the brackets at the RHS.

5 - 2 - 3x = x + 2x + 2

3 - 3x = 3x + 2

Group like terms and make x the subject.

3 - 2 = 3x + 3x

1 = 6x

x = 1/6

What is x given triangleABC ~triangleDBE?
denis-greek [22]

x = 37.5 (or) \frac{75}{2}

Solution:

Given \triangle A B C \sim \triangle D B E.

Let us take BE = x and BC = 25 + x.

To determine the value of x:

If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.

$\frac{AC}{DE}=\frac{B C}{B E}

$\frac{50}{30} =\frac{25+x}{x}

Do cross multiplication, we get

50x=30(25+x)

50x=750+30x

Subtract 30x from both sides of the equation.

20 x=750

Divide by 20 on both sides of the equation, we get

x = 37.5 (or) \frac{75}{2}

Hence the value of x is 37.5 or \frac{75}{2}.

Find the product.<br> (y - 2bs^2) (y + 3bs^2)<br> Enter the correct answer.
Vikentia [17]

Answer:

y² + bs²y - 6b²s⁴

General Formulas and Concepts:

  • Expand by FOIL (First Outside Inside Last)
  • Exponent Power Rule: (b^m)^n=b^{mn}

Step-by-step explanation:

<u>Step 1: Define expression</u>

(y - 2bs²)(y + 3bs²)

<u>Step 2: FOIL</u>

  1. First:               y · y = y²
  2. Outside:         y · 3bs² = 3bs²y
  3. Inside:            -2bs² · y = -2bs²y
  4. Last:               -2bs² · 3bs² = -6b²s⁴

<u>Step 3: Simplify</u>

  1. Combine:                         y² + 3bs²y - 2bs²y - 6b²s⁴
  2. Combine like terms:        y² + bs²y - 6b²s⁴
