Answer:
X= 5, -9
Step-by-step explanation:
(X+2)² =49
Expand the bracket,
(X+2) (X+2)= 49
Apply the distributive property;
X(X+2) +2 (X+2) =49
X²+2X+2X+4=49
X²+4X+4=49
Move 49 to the left side of the equation;
X²+4X+4-49=0
X²+4X-45=0
Apply Factorisation method;
Consider the form
a²+bx+c=0
Find two numbers whose sum is equal to b and whose product is equal to c.
Comparing with our equation;
B =4 and C =45
We can use 9 and -5, this is because ;
9+(-5)=4 and 9*(-5)= 45.
Replace X +4X-45=0 with (X-5) (X+9)=0
Therefore;
X-5=0
X+9=0
Moving to the left side of the equation;
Therefore X= 5 and -9
Hi!
So what you want to do is to find the perimeter add the sides up 4 times or mutiply 3.5 and 4. It's the same thing
Perimeter: 3.5*4= 14
For area multiply 2 sides and only 2 sides which are the length and width
Area: 3.5 * 3.5 = 12.25
Hope this helps!!
Answer:
30%
Step-by-step explanation:
Think of the 10 as 100%. 2 as 20% and so on. The green makes up 30%.
Answer:
Arc KL
Arc OM
Step-by-step explanation:
We know that Angle NPM is equal to 90 degrees.
Therefore, Angle KPM is also equal to 90 degrees.
We are told that Arc LM is equal to 67.
Thus, the measure for Arc KL is equal to
We also know that Angle OPN is equal to Angle KPL.
Therefore, the measure of Arc ON
Using that information, we know that Arc OM is equal to
