Step-by-step explanation:

here \: given \: that \: total \: lenth = bd = 67 \\ then \: bd = bc + cd \\ so \: we \: can \: write \: that \\ 67 = 3x - 2 + 4x + 13 \\67 =  3x + 4x - 2 + 13 \\ 67 = 7x + 11 \\ 7x = 67 - 11 \\ 7x = 56 \\ x =  \frac{56}{7}  \\ x = 8 \\ thankyou

Answer:

\huge\boxed{\sf 22}

Step-by-step explanation:

By looking at the line segment, we get to know that:

BD = BC + CD

<u>Given that:</u>

BD = 67

BC = 3x - 2

CD = 4x + 13

<u>Solution:</u>

Put the givens in the above equation made.

67 = 3x - 2 + 4x + 13

67 = 3x + 4x - 2 + 13

67 = 7x + 11

7x = 67 - 11

7x = 56

Divide both sides by 7

x = 56 / 7

x = 8

<u>Now, Finding BC:</u>

= 3x - 2

Put x = 8

= 3(8) - 2

= 24 - 2

= 22

Answer:

1/2 - 3(1/2 + 1)²

simplify the expression (1/2 + 1)

1/2 - 3•(3/2)²

using PEMDAS, we see we have to evaluate the exponent first

(3/2)² = 9/4

rewrite the equation

1/2 - 3 • (9/4)

multiply 3 by (9/4)

1/2 - (27/4)

subtract

-25/4

(1 + 1/3)² - 2/9

simplify the expression (1 + 1/3)

(4/3)² - 2/9

using PEMDAS, we see we have to evaluate the exponent first

(4/3)² = 16/9

rewrite the equation

(16/9) - (2/9)

subtract

14/9

Answer:

The expression contains FOUR terms and each term contains TWO factors.

Step-by-step explanation:

In algebra, the word term refers to single numbers(10),  variables<em>(</em><em>y</em><em>)</em> also the product of the two(<em>10y</em>).

In the given expression : <em>ab+cd+ef+gh .</em>

We have four terms;

  • ab
  • cd
  • ef
  • gh

A factor is part of a product. For the given equation we Four terms each term will have two factors.

  • <em>ab</em>- is a product of factor a and b
  • <em>cd- </em>is a product of factor<em> c </em>and<em> d</em>
  • <em>ef-</em>is a product of factor<em> e </em>and<em> f</em>
  • <em>gh-</em>is a product of factor<em> g </em>and<em> h </em>
