Answer:
s for length of either equal side
b for the unequal side
b=-2+2*(s+s) and 2s+b=40
b=2*2s-2
b=4s-2
2s+4s-2=40
6s-2=40
6s=42
s=7
b=4*7-2
b=28-2
b=26
Answer:
A
Step-by-step explanation:
Rotate it 90 degrees and it would be laying on the x axis on the 2 quadrant and when you flip it on the x axis it would become A
Binomial 
when added to polynomial 
gives polynomial that does not contain the variable y .
<h3>What is binomial?</h3>
A mathematical expression consisting of two terms connected by a plus sign or minus sign .
Example: x + 2 is a binomial, where x and 2 are two separate terms.
<h3>What is polynomial?</h3>
A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer
According to the question
polynomial
when added with
= 
(as 
got cancelled )
that does not contain the variable y
Hence, Binomial when added to polynomial gives that does not contain the variable y .

# SPJ2
-2n + 1.8 = 3.2
Subtract 1.8 from both sides
-2n = 1.4
Divide both sides by -2
n = 1.4/-2 = 0.7/-1 = -0.7
n = -0.7
Check your work:
-2(-0.7) + 1.8 = 3.2
1.4 + 1.8 = 3.2
3.2 = 3.2
The answer is B. -0.7
Answer:
k = log9 / log 0.66
k = 5.3
Step-by-step explanation:
Please always remember that, when an exponential equation is given with different bases, the best approach is to take log of both sides.
If you have a calculator handy, that would be pretty fast and easy.
0.66 ^ k = 9
Take log of both sides:
klog 0.66 = log 9
k = log 9 / log 0.66
k = 0.954 / - 0.18
k = -5.3
