Answer:
area 1
Step-by-step explanation:
Answer:
99cm^2
Step-by-step explanation:
When finding an area of a triangle, you multiply base times height and then divide by 2.
In this case,
Height:11
Base: 18
So then apply the formula:
Solve (using a calculator lol)
We get 99
Don't forget units!
So the final answer is 99cm^2
Answer:
C) isosceles triangle
Step-by-step explanation:
equilateral triangle has all sides the same and all angles the same
180/3 = 60 so each angle is 60 degrees
A) obtuse triangle
means it has an angle bigger than 90 degrees
B) right triangle
that means it has an angle at 90 degrees
C) isosceles triangle
That means it has 2 sides that are the same
D) scalene triangle
that means it has no sides the same
If it has 3 sides the same. it must have 2 sides the same. So any equilateral triangle must be an isosceles triangle
Answer:
6x^2 -2x
Step-by-step explanation:
As written, the constant terms in the first factor cancel each other. The distributive property is used to perform the multiplication:
(3x^2 +1 -1 -x)(2) = (3x^2 -x)(2) = (3x^2)(2) -x(2)
= 6x^2 -2x
