Answer: Subtract 6 from both sides. Then, one would get 3x=15. Divde by 3 on both sides. x=5.
Step-by-step explanation:
Answer:
A) 20°
Step-by-step explanation:
Sine and cosine are co-function complements which means that value of sine of an angle is equal to the value of cosine of the complementary angles.
This can be represented by:


Given statement:

Applying co-function complements

Since, we can represent 70° = 90°-20°
So
Thus,
makes the statement true.
Lateral area = Perimeter x height
Lateral area = (2 + 7 + 7.28) x 31 = 16.28 x 31 = 505 m²
Surface area = 2(1/2 x 2 x 7) + 505 = 519 m²
Answer: Lateral area = 505 m² ; Surface area = 519 m²
Answer: x=6
Step-by-step explanation:
3(5-2x)-3x=3
-15+6x-3x=3
-15+3x=3
3x=3+15
3x= 18
x=6
Answer:
B.3x2 - 4
Step-by-step explanation:
(f+g)(x) ➡ f(x) +g(x)
add up the functions
2x2 + 3 + x2 - 7 = 3x2 - 4
