Answer:
The distributive property says that when there is a number outside of parenthesis, this means it should be distributed (or multiplied) to the values inside the parenthesis.
So in this situation, 10 x b = 10b
and 10 x 4c = 40 c
so 10(b + 4c) becomes 10b + 40c once the 10 is distributed within the parenthesis.
I hope this helps!
Step-by-step explanation:
2x + 9° + 3x + 1° =180° (opposite angles of a cyclic quadrilateral are supplementary)
5x + 10° = 180°
5x = 180° - 10°
5x = 170°
x = 34°
Now
Angle A
= 2 * 34° + 9°
= 77°

Answer:5.6
Step-by-step explanation:2.8×12=12×9.8-8/3v^2
33.6=117.6-8/3v^2
8/3v^2=117.6-33.6
8/3v^2=84
8v^2=84×3
8v^2=252
V^2=31.5
V=√31.5
V=5.6125
V~5.6
I think this is the answer
Answer:
-14
Step-by-step explanation:
substitute 4 for x
28(4) - 9 (2(4)+ 6)
multiply
112-9(8+6)
add numbers
112-9(14)
multiply
112-126
subtract
-14
