Answer: 2.25x

Scientific notation is used in science because the number can be vary from so much that using decimal is making it hard. The number expressed in

form. Both number in the question is already in scientific notation. Then to multiply the number and keep it at scienfitic notation the calculation should be:
2.5 x

x 9 x

= 22.5 x

= 2.25x

Answer:
x= 110°
Step-by-step explanation:
if you continue drawing the top purple line you will have a triangle with three angles
70° ; is given
180-140= 40°; is the same angle as the supplement angle of 140° (complementary angles are congruent)
180-70-40 = 70°; because sum of angles in a triangle is 180°
So angle x= 180 -70 = 110 because are a linear pair
2(x4) = 35 - (7-4x)
+4x
2(x8)= 28
/2 /2
8x = 14
Answer:82+31=113 180-113=67 so the answer is 67
