The first one the pattern is times 4. the next three numbers would be 192, 768, 3072.
the second on the pattern is plus 13. the next three numbers would be 58, 71, 84.
Answer:
6x^2 -29 +35.
Step-by-step explanation:
use the FOIL method(First, Outer,Inner, and Last.)
2x x 3x=6x^2.
2x x -7=-14x.
-5 x 3x =-15x.
-5 x -7=35.
= 6x^2 -14x -15x+35
6x^2 -29x +35.
For this case we have the following expression:
We apply distributive property:
We rewrite in equivalent form:
Answer:
Use the sine rule.
For any triangle: sin(a) / A = sin(b) / B = sin(c) /C
Where A is the side opposed to angle a, B is the side opposed to angle b, and C is the side opposed to angle c.
Here, sin(B) / AC = sin(A) / BC = sin (C) / AB
<span> BC = 12.35, AC = 8.75 centimeters, and m∠B = 37°
sin(37) / 8.75 = sin(A) / 12.35 => sin (A) = 12.35 * sin(37) / 8.75
sin(A) = 0.845 = A = arctan(0.845) = 58.15°
And A + B + C = 180° => C = 180 - A - B = 180 - 58.15 - 37 = 84.85
Answer:
measure of angle A = 58.15°
measure of angle C = 84.85 °
