A) the perimeter of a triangle is the bottom plus the left slanty side plus the right slanty side, but you need the bottom in ft so that would be 6 ft. the perimeter is 13 ft

b) 1 yard

Add.<br> (-x^3+26x^2-7-13)+(6x^4-x^3+8x+27)<br> express the answer in standard form.

$(-x^3+26x^2-7-13)+(6x^4-x^3+8x+27)\\\\=-x^3+26x^2-7-13+6x^4-x^3+8x+27\\\\=6x^4+(-x^3-x^3)+26x^2+8x+(27-7-13)\\\\=\boxed{6x^4-2x^3+26x^2+8x+7}$

The Mendes family bought a new house 8 years ago $129,000. The new house is now worth $186,000. Assuming a steady rate of growth

USPshnik [31]

So assuming simplet interest

find the change to find the interest
change=186000-129000=57000

simple interest=time times rate times principal
time is in years (8)
rate is in decimal
principal is amount invested (129000)

so
interest is 57000
57000=(8)(r)(129000)
57000=1032000r
divide both sides by 1032000
0.05523255813953488372093023255814=r
or
5.523255813953488372093023255814%
rounded
5.5%

Can someone solve this for me????? (10−523)⋅(−2)+x=823

AleksandrR [38]

Answer:The answer is x = -203.

Step-by-step explanation:

1. reduce brackets

2. reduce 10 - 523 to -513

3. reduce -513 x -2 to 1026

4. subtract 1026 from both sides

5. reduce 823 - 1026 to -203
