Answer:
I would use cubic meters :)
Step-by-step explanation:
Answer:
∠W = 16.3°
Step-by-step explanation:
In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.
From that above question, we are given 3 sides and we are to find the angle of one of the sides.
We solve using Cosine rule.
∠W = arc cos (v² + x²﹣w²/2vx)
∠W = arc cos (64² + 63² - 18² /2 × 64 × 63)
∠W = arc cos (0.9599454365)
∠W = 16.27137°
∠W = 16.3°
multiply the binomials:
(x + 3y) (3x - 2y)
Answer:
Simplify the expression:
3x^2+7xy−6y^2
Steps:
3x·2+7xy-6y·2
Multiply the numbers: 3·2=6
=6x+7xy-6·2y
Multiply the numbers: 6·2=12
=6x+7xy-12y
