Answer:
Step-by-step explanation:
Given parameters:
Dimensions of the equilateral triangle = 6.2cm
Unknown:
Perimeter = ?
Solution:
The perimeter of the triangle is the sum of all its sides;
Perimeter = 3(L) for an equilateral triangle;
Perimeter = 3(6.2) = 18.6cm
to the nearest mm = 19.0cm
Answer:
24
Step-by-step explanation:
X + (X + 2) = 50
2X = 50 - 2
2X = 48
X = 24
Answer: 10
Solution:
60/12 = 5
2 x 5 = 10
f(x) = 3x²
g(x) = 4x³ + 1
f(g(x)) = 3.(4x³ + 1)²
As we know
(a + b)² = a² + 2.a.b + b²
So,
(4x³ + 1) = (4x³)² + 2.4x³.1 + 1² =
f(g(x)) = 3.()
The degree is the maximum exponent, so, 6.
2a-4 = 3a-15
2a = 3a - 11
-1a = -11 , a = 11
