Answer: B
Step-by-step explanation:
If this helps, please mark brainylist.
The whole thing equals 90 degrees, one side is 65 degrees. We plug in 10 to 2x + 5. That will give us 25. 25 + 65 = 90.
Part a is 105 and part b is 180
Hello,
Let's take a point of d:y=-x+5
if x=0 then y=5 : A=(0,5)
The perpendicular of d passing through A is
y-5=1(x-0) since the slope is -1*?=-1==>?=1
y=x+5
Intersection with the line d':y=-x-9 is
y=x+5 and y=-x-9 ==>x+5=-x-9==>2x=-14==>x=-7 and y=-7+5=-2
B=(-7,-2)
The middle of [AB] is C=((0+(-7))/2,(5+(-2))/2)=(-3.5,1.5)
The line parallele at d passing through C is
y-1.5=-1(x+3.5)==>y=-x-2
Note: Since you have not added the expression, so I am taking a sample expression which anyways would help you clear your concept regarding factors.
Answer:
Assuming the expression
- The expression consists of two terms. i.e. and .
- and are factors of the expression .
Step-by-step explanation:
Lets us consider an expression
Observe that and are connected by addition. Thus, are terms. So, The expression consists of two terms. and .
Next, let's have some discussion about factors in a mathematical expression.
Factors are said to be the parts of the expression which are connected by multiplication.
Now lets solve the example to determine the factors
∵
Therefore, and are factors of the expression .
