2nd angle measures 50
90 is the total so all that was needed is to subtract 40 from 90
Answer:
answer is 0
Step-by-step explanation:
You need to isolate y. When you do, will get y=(4/3)x-2. When the equation is in this form, you can see that the slope is 4/3
Answer:
The expression 
can be combined because of the commutative property of addition.
Step-by-step explanation:
A monomial is a number, a variable or a product of a number and a variable where all exponents are whole numbers. That means that
all are examples of monomials.
The commutative property of addition says that changing the order of addends does not change the sum.
If we add ![[(a + b)+ c]](https://tex.z-dn.net/?f=%5B%28a%20%2B%20b%29%2B%20c%5D)
or ![[a + (b + c)]](https://tex.z-dn.net/?f=%5Ba%20%2B%20%28b%20%2B%20c%29%5D)
, the result will be same.
Therefore,
Answer:
<u>Width = 7 inches</u>
<u>Length = 23 inches</u>
Step-by-step explanation:
Let :
Equating to area :
- (2x + 9)(x) = 161
- 2x² + 9x = 161
- 2x² + 9x - 161 = 0
- 2x² - 14x + 23x - 161 = 0
- 2x(x - 7) + 23(x - 7) = 0
- x - 7 = 0
- x = 7
Dimensions are :
- <u>Width = 7 inches</u>
- Length = 2(7) + 9
- <u>Length = 23 inches</u>
