Answer:
Triangle ABE and triangle CDE are congruent by using SAS theorem.
Step-by-step explanation:
It is given that e is the midpoint of BD and 
.
(E is midpoint of BD)
Angle AEB and angle CED are vertical opposite angle and the vertical opposite angles are always same.
(Given)
So by using SAS theorem of congruent triangles.
Therefore triangle ABE and triangle CDE are congruent by using SAS theorem.
Answer:
for a) the following answers are in order from left to right.
5, 2, 2, and 10
for b) this is the square root of three: 1.73205080757 [u can round it to the first decimal place urself! :)]
Step-by-step explanation:
b) 4 = x^2 + 1
4 - 1 = x^2 - 1
3 = x^2
so the sqaure root for 3 is 1.73205080757
13x+6y = -30................y = -5 -13x/6
x−2y=−4...................... y = x/2 +2 <span>
If we graph both lines we can get the solution of the system (point of intersection)
The best estimate is (x,y) = (-2.625, 0.688)</span>
Time taken by Ria to paint a room = 4 hours
Time taken by Destiny to paint a room = 6 hours
If they work together, they complete 1 job. So,
The LCD of 4 and 6 is 12
Hence, both of them can paint the room in 
hours or 2.4 hours.
Answer:
-600
Step-by-step explanation:
4 x 10 x 3 x 5 x -1
40 x 15 x -1
600 x -1 = -600
