b (-7, -9) and d (5, 15) are both ordered pairs that satisfy the function of y=2x+5. i hope this helps you :))
Answer:
Length of the side opposite to angle 
is 31.49
Step-by-step explanation:
Included angle can be defined as the angle in between two sides of the triangle.
So angle is in between sides 16 and 21.
Refer to the attachment for triangle diagram.
To find the length of opposite side, use cosine rule as follows
From the diagram, 
Substituting the values in the formula,
Simplifying,
Taking square root on both sides,
Therefore length of third side is 31.49
X^2 -15x +54 = 0 for you can factor it easy just you need getting two numbers with sum equal -15 and product equal 54
-15= (-9)+(-6) and (-9)*(-6)= -54 in this way will get
x^2 -15x +54 = (x-6)(x-9)
hope helped
I'll say the first integer is x. The next consecutive odd number would be x+2. If the sum of the odd integers is 236, the equation would be
x + (x + 2) = 236
solve for x
2x + 2 = 236
subtract 2 from each side of the equation
2x = 234
divide both sides by 2
x = 117
117 is the first odd integer. to find the other integer (x + 2), substitute 117 for x, and you have 117 + 2, which equals 119
The two consecutive odd integers that add up to 236 are 117 and 119.
