The expression represented by 50 added to half of a number, c is 50 + c/2

<h3>What are expressions?</h3>

Expressions are mathematical statements that are represented by variables, coefficients and operators

<h3>How to translate the algebraic expression?</h3>

The expression is given as

50 added to half of a number, c

half of a number, c means divide c by 2

So, we have

50 added to half of a number, c => 50 added to c/2

Added to means +

So, we have

50 added to half of a number, c => 50 + c/2

Hence, the expression represented by the statement is 50 + c/2

Paladinen [302]

Answer:

$\large\boxed{s(x)\cdot t(x)=2x^3+11x^2+8x-16}$

Step-by-step explanation:

$s(x)=2x^2+3x-4,\ t(x)=x+4\\\\s(x)\cdot t(x)\\\\\text{use the distributive property:}\ a(b+c)=ab+ac\\\\s(x)\cdot t(x)=(2x^2+3x-4)(x+4)\\\\=(2x^2+3x-4)(x)+(2x^2+3x-4)(4)\\\\=(2x^2)(x)+(3x)(x)+(-4)(x)+(2x^2)(4)+(3x)(4)+(-4)(4)\\\\=2x^3+3x^2-4x+8x^2+12x-16\\\\\text{combine like terms}\\\\=2x^3+(3x^2+8x^2)+(-4x+12x)-16\\\\=2x^3+11x^2+8x-16$

Describe how you would find the third angle measure in a triangle knowing that one angle measures 63 degrees and the the other m

maxonik [38]

the missing angle is $c=69$ ° .

<u>Step-by-step explanation:</u>

Here we have , a triangle knowing that one angle measures 63 degrees and the the other measures 48. We need to tell e what the missing angle measure must be. Let;s find out :

We know that , by the property of triangle : Sum of all the three angles of a triangle is always 180° . Let angles of triangle be a,b,c :

⇒ $a+b+c=180$

In question we have following parameters as :

$a=63\\b=48\\c=?$

Putting these value in $a+b+c=180$ we get :

⇒ $a+b+c=180$

⇒ $63+48+c=180$

⇒ $111+c=180$

⇒ $c=180-111$

⇒ $c=69$ °

Therefore , the missing angle is $c=69$ ° .

Evaluate each expression

azamat

Answer:

See below.

Step-by-step explanation:

<u>Question 1</u>

a = -2 and x = -6

| a + x | / 2 - | a - x | / 2

| -2 + -6 | / 2 - | -2 + 6 | / 2

| -8 | / 2 - | 4 | / 2

8/2 - 4/2

= 4/2

= <u>2</u>

<u></u>

<u>Question 2</u>

a = -5, b = 4, c = 1, d = -3

| a - b | - | c + d |

| -5 - 4 | - | 1 - 3 |

| -9 | - | -2 |

= 9 - 2

= <u>7</u>
