Find the area of the triangle. 3 cm 11 cm C с 14.5 cm

boyakko [2]

Answer: The answer is 43.5 because when using the formula you get this result.

Step-by-step explanation: Area of triangle is base x height divided by 2. So do our base 14.5 and our height 6 and multiply them together. 14.5 x 6 = 87 / 2 = 43.5

-5(2 – 5n) + 6 = -5n - 34 -02

statuscvo [17]

Answer:

Assuming you're solving for n, 1. n=-1 2. n=-1.6

Step-by-step explanation:

1. -5(2-5n)+6=-5n-34-2

Distributive Property

-10+25n+6=-5n-32-2

Add Like Terms

-4+25n=-5n-34

Subtract -4

25n=-5n-30

Subtract -5n

30n=-30

Divide by 30

n=-1

2. -5(2-5n)+6=-5n-34-20

Distributive Property

-10+25n+6=-5n-32-20

Add Like Terms

-4+25n=-5n-52

Subtract -4

25n=-5n-48

Subtract -5n

30n=-48

Divide by 30

n=-1.6

Help me with my math pls :)

MrMuchimi

Answer:

4(x-8)=-32+4: x=1

2(x-2)=-3-2x: x1/4

3+5x=5(x+2)-7: x=0

8x+38=-3(-6-4x) x=5

Step-by-step explanation:

4(x-8)=-32+4

add subtract the numbers

-32+4=-28

4(x-8)=-28

Divide both sides by 4

$\frac{4(x-8)}{4}=\frac{-28}{4}$

Simplify

x-8=-7

Add 8 on both sides

x+8-8=-7+8

Simplify

x=1

2(x-2)=-3-2x

Expand 2(x-2)
apply distributive law: a(b-c)=ab-ac

a=2 b=x c=2

=2x-2·2

multiply the numbers

2·2=4

=2x-4

2x-4=-3x-2

Add 4 to both sides

2x-4+4=-3-2x+4

simplify

2x=-2x+1

Add 2x on both sides

2x+2x=2x+1+2x

Simplify

4x=1

Divide by 4 on both sides

4x÷4=1÷4

Simplify

x=1/4

3+5x=5(x+2)-7

We move all terms to the left:

3+5x-(5(x+2)-7)=0

We calculate terms in parentheses: -(5(x+2)-7), so:

5(x+2)-7

We multiply parentheses

5x+10-7

We add all the numbers together, and all the variables

5x+3

Back to the equation:

-(5x+3)

We get rid of parentheses

5x-5x-3+3=0

We add all the numbers together, and all the variables

=0

x=0/1

x=0

8x+38=-3(-6-4x)

Simplifying

8x + 38 = -3(-6 + -4x)

Reorder the terms:

38 + 8x = -3(-6 + -4x)

38 + 8x = (-6 * -3 + -4x * -3)

38 + 8x = (18 + 12x)

Solving

38 + 8x = 18 + 12x

Solving for variable 'x'.

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

Add '-12x' to each side of the equation.

38 + 8x + -12x = 18 + 12x + -12x

Combine like terms: 8x + -12x = -4x

38 + -4x = 18 + 12x + -12x

Combine like terms: 12x + -12x = 0

38 + -4x = 18 + 0

38 + -4x = 18

Add '-38' to each side of the equation.

38 + -38 + -4x = 18 + -38

Combine like terms: 38 + -38 = 0

0 + -4x = 18 + -38

-4x = 18 + -38

Combine like terms: 18 + -38 = -20

-4x = -20

Divide each side by '-4'.

x = 5

Simplifying

x = 5

Hope this helps

In 2015, the population of a district was 10,600. With an annual growth rate of approximately 4%, what will the population be in

Murljashka [212]

Answer:

$19,090\ people$

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$y=a(1+r)^x$

where

y is the population

x is the time in years since year 2015

a is the initial value

r is the rate of change

we have

$a=10,600\\r=4\%=4/100=0.04$

substitute

$y=10,600(1+0.04)^x$

$y=10,600(1.04)^x$

In the year 2040 the value of x is equal to

$x=2040-2015=25\ years$

substitute

$y=10,600(1.04)^{15} =19,090\ people$
