Answer:
395.2 cm²
Step-by-step explanation:
2x12.7x6.72=170.688
2x6.72x5.78=77.6832
2x5.78x12.7=146.812
170.688+77.6832+146.812=395.1832
Answer:
<h2>
y = 6x - 1</h2>
Step-by-step explanation:
(0, -1) ⇒ x₁ = 0, y₁ = -1
(1, 5) ⇒ x₂ = 1, y₂ = 5
So the slope:
The slope-intercept form of the equation of line is y = mx + b, where m is the slope and b is the y-intercept of the line.
(0, -1) ⇒ x₀ = 0, y₀ = -1 ⇒ b = -1
Therefore:
y = 6x - 1 ← the slope-intercept form of the equation

Answer:
No. Se below for explanation
Step-by-step explanation:
If it is a right triangle it sides must meet the Pitgoras Theorem, wich says that the legs squared when summed must be equal to the square of the hypotenuse. Here the legs would be the sides of length 10 and 18, as the hypotenuse is always the longest. So we need to see:
10^ 2 + 18^2 = x
if x is equal to 21^2, so we can have a right triangle, if not, we cannot.
10^ 2 + 18^2 = 100 + 324
10^ 2 + 18^2 = 424
But:
21^2 = 441
So, as 10^2 + 18^2 < 21^2 this can not be a right triangle.
