Explanation: the interior angles of a triangle equal 180.
Answer:
5unit
Step-by-step explanation: since area of rectangle = length*width
Here length is (x+2) and width is(2x+3)
(x+2)(2x+3)=91
On further solving
2x^2+75x-85=0
2x^2-10x+17x-85=0
2x(x-5)+17(x-5)=0
(2x+17)(x-5)=0
x=5unit
Answer:
<h2>-1/5</h2>
Step-by-step explanation:
Starting at -3/5 you need to subtract -2/5.
When you subtract a negative number, the sign flips and you add instead. Often, you are taught that two similar signs means add and two opposite signs mean minus.
<em>+ + = +</em>
<em>- - = -</em>
<em>+ - = -</em>
<em>- + = -</em>
<em />
This means -3/5 - -2/5 becomes -3/5 + 2/5.
Because you are adding, you move two lines to the right on the number line.
You end at -1/5.
Answer:
-226,981
Step-by-step explanation:
This is how you do it.
First, you do 3-2 which is 1.
Then, you do 3-4 to the 3rd power which is -61.
After, you do 1*-61 because there are parenthesis, which equals -61.
Then, you do -61, which is the total of everything in parenthesis, and do it times the power of 3 to get -226,981.
Hope it helps!!^_^
