First one is 2
(9x - 7 = 3x + 5
9x - 3x = 5 + 7
6x = 12
x = 12/6
x = 2)
Second one is 35°
( measure of Angle ABC = measure of Angle DBE
measure of Angle ABC = 35°
Therefore measure of Angle DBE = 35° (Since its equal))
Answer:
10r + 5s and the second one stays the same because 0.5 doesn't have the variable x so u leave it the same. Hope this helps
Step-by-step explanation:
Answer:
-If the legs of the triangle added up are bigger than the hypotenuse, its an acute tri.
-if they are smaller then its and obtuse angel
-if the legs added up are = to the hypotenuse, then the triangle Is a right triangle.
your right triangle is:
5,12,13
Step-by-step explanation:
Because 5^2+12^2=13^2
It is true
Answer:
-6
Step-by-step explanation:
f(x) = x^2 + 5x
Let x = -2
f(-2) = (-2)^2 + 5(-2)
= 4 -10
= -6
