Answer:
Step-by-step explanation:
Factorize means convert and expression into multiple factors.
You have to find to factor that multiplied equals the original equation. Firts of all you split the expression of square X into 3X an X, so you guarantee that when you multiply 3X by X, the result is 3X^2.
After doing that, you need to think in numbers that equals the middle term (8X) and the constant (5).
-1 and -5 guarantee you that the multiplication of them results into +5, so you start with those numbers. Then you have to find where to put them in order to find the -8X.
-5 x X = -5X
-1 x 3X = -3X
And adding those two expresion you find the -8X that you need!
Please try to solve it multiplying term by term and check the final equation.
Answer:
400
Step-by-step explanation:
Initial velocity of the plane is Vo = 0.
acceleration a = 1.3 m/s2
total distance = 2.5 km = 2500m
time taken to reach 2.5 km with 1.3m/s^2 acceleration = t
S = Vo t + 0.5 a t^2
2500 = 0 + (0.5*1.3* t^2)
t^2 = 3846.15
t = 62 s
the maximum velocity plan can reach within 62 s is Vt
Vt = Vo + a t
Vt = 0 + (1.3*62)
Vt = 80.6 m/s
Since 80.6 m/s is greater than 75 m/s, plane can use this runway to takeoff with required speed.
<span>x^0 y^-3 / x^2 y^-1
= 1 / </span> x^2 y^-1 (y^3) ...because x^0 = 1 and [(y^-1) (y^3)] = y^2<span>
= 1/(x^2 y^2)</span>
Answer:
432 cm²
Step-by-step explanation:
To find the surface area of a cuboid, there is a formula.
2lw+2lh+2hw
Length is l, height is h, and width is w.
2(12)(8)+2(12)(6)+2(6)(8)
Multiply all the terms.
336+96
Add both the terms.
= 432
The surface area of the open cuboid is 432cm².
