the equation for the triangle can be this

2(2x+3)+10x-5 = 180

Answer:

x= 16

x=1.5

Step-by-step explanation:

Simplifying

3x + -0.5 = 0

Reorder the terms:

-0.5 + 3x = 0

Solving

-0.5 + 3x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '0.5' to each side of the equation.

-0.5 + 0.5 + 3x = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0

0.0 + 3x = 0 + 0.5

3x = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5

3x = 0.5

Divide each side by '3'.

x = 0.1666666667

Simplifying

x = 0.1666666667

Simplifying

2x + 3 = 0

Reorder the terms:

3 + 2x = 0

Solving

3 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + 2x = 0 + -3

2x = 0 + -3

Combine like terms: 0 + -3 = -3

2x = -3

Divide each side by '2'.

x = -1.5

Simplifying

x = -1.5

Which expression represents a simplified form of the algebraic expression shown below?

1/2(2x +4) + x

Question 2 options:

x + 2


2x + 4


2x + 2


3x + 2

Answers

Answer:

2x+2

Step-by-step explanation:

First you want to distribute

1/2(2x+4)

ignore the ending +x for now

Distribute 1/2 to 2x

since 2*1/2 is 1 then we get 1x, or x

next distibute 1/2 to 4

you get +2 since 1/2*4=2

so what you end up with is x+2

However, you still have the +x from the beginning

x+2+x

Imagine that each x has a one in front

1x+2+1x

now re arrange so the common factors are near each other

1x+1x+2

now add the common factors

1x+1x=2x

and finally you get 2x+2

Answers

The first part you would add the -1/16 with -11/16 to get an answer of -12/16. Fill in the first blank from the left to be 11 so it is 11/16. The other blank in that row should be a 1 like it is in the original equation.
Second row blank would become 12 because 11+1 =12. The third row of blanks would then simplify 12/16 to be 3/4 because both 12 and 16 can be divided by 4 to make 3 and 4 respectively.
-3/4 + -1/4 equals -1 because -4/4 simplifies to -1.

In triangle,ADB

p(perpendicular)=BD=12 cm

h(hypotenuse)=AB=15cm

b(base)=AD=??

Let the AD be x

Using Pythagorean theorem,

[tex]{p}^{2} + {b}^{2} = {h}^{2} \\

=>{12}^{2} + {x}^{2} = {15}^{2} \\

=>144+{x}^{2}=225\\

=>{x}^{2}=225-144\\

=>{x}^{2}=81\\

=>x= \sqrt{81} \\

=>x= \sqrt{9×9} [/tex]

Hence,x=AD=9

So,AC=AD+DC=9+16=25.
