#19 is B:100 and #20 is H:30 I believe, if those were the answers you were looking for :)
Answer:
All real numbers of x.
Step-by-step explanation:
5x+10=5(x+2) have the exact same equations on both sides.
5x+10=5x+10
If both are graphed, they will intersect each other for every value of x.
Answer:
50cm squared
Step-by-step explanation:
Imagine the width is 'a'
Then the length will be 2a as it's twice as wide as it's long.
The formula for perimeter is 2(L+W)
If we subsitute the algebra/numbers in we get
P = 2(L+W)
30 = 2(2a+a)
30 = 2(3a)
30 = 6a
5 = a
a = 5cm
Then the area is the following
A = LW
A = 2a(a)
A = (2(5))(5)
A = 10(5)
A = 50cm squared
Answer:
Step-by-step explanation:
Given
Required
Create a function table for inputs -2, 0, 2 and 4
When x = -2
When x = 0
When x = 2
When x = 4
So, the table is:
It’s larger than a 90 angle it has a bigger angle
