Answer:
y = 4
Step-by-step explanation:
distribute
10 + 2y = 18
minus 10 from both sides
2y = 8
divide by 2
y = 4
Answer:
18
You first have to find out the formula A= bh
6x8 is 18 so the answer is 18.
Answer:
Looking at the given points we know that it is going to be a triangle because it only have 3 points. Therefore the figure is a triangle and the area formula would be 
.
You can look at the attached graph and what we see is that our height of the triangle is from 
to 
which means that our height is 7 units high. We can also see that our base starts at 
and ends at 
making us have a base of 8 units.
<u>We then plug in the values and solve</u>
Therefore, the area of our triangle is 
Hope this helps! Let me know if you have any questions
Answer:
(5 -b)^4 = b^4 -20b^3 +150b^2 -500b +625
Step-by-step explanation:
The applicable rules of exponents are ...
√a = a^(1/2)
(a^b)^c = a^(bc)
__
You have √((5-b)^8) = ((5 -b)^8)^(1/2)
= (5 -b)^(8/2) = (5 -b)^4
Sometimes, "simplify" means "remove parentheses".
(5 -b)^4 = b^4 -20b^3 +150b^2 -500b +625
Answer:
$149.60
Step-by-step explanation:
12% = .12
.12 × 170= 20.40
$170- 20.4= $149.60
