Answer:
x=55
Step-by-step explanation:
(2x+10) + (x+5) = 180
3x+15=180
3x=165
x=55
Answer: Hi!
Remember, when you're subtracting a negative, that's equal to adding a positive. So -2-(-17) is actually equal to -2 + 17!
-2 + 17 = 15
The expression -2-(-17) is equal to 15.
Hope this helps!
Answer: D
Step-by-step explanation:
A counterexample is an isosceles trapezoid.
Question:
Iliana multiplied 3p – 7 and 2p^2 – 3p – 4. Her work is shown in the table.
Which is the product?
6p^3 + 23p^2 + 9p + 28
6p^3 – 23p^2 – 9p + 28
6p^3 – 23p^2 + 9p + 28
6p^3 + 23p^2 – 9p + 28
Answer:
Option C: 
is the correct answer.
Explanation:
The two expressions are 
and 
The product of the expression can be determined by multiplying each of the first term with the second term of the expression, we get,
Simplifying we have,
Adding the like terms, we have,
Thus, the product of the two expression is
Hence, Option C is the correct answer.
Answer:
The points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects.
Step-by-step explanation:
It is the last option. The perpendicular bisector theorem states that if a point lies on the bisector of a segment it is equidistant from the endpoints.
Meaning
If a perpendicular bisector is a line of the side of the triangle , it bisects the sides forming two right angles .
The first three choices are incorrect because
1) the figure shows a triangle bisected into two triangles and option 1 tells about 1 isosceles triangle.
2) The base angles of any triangle can be different or same .
3) the three perpendicular bisectors meet at a point called the circumeter. We have 1 perpendicual bisector which is dividing the triangle into two equal triangles.
