Answer:
13.8 cm
Step-by-step explanation:
the sides of the triangle measure 3.6, 5.7,4.5cm?
So, we have
perimeter is 3.6 + 5.7 + 4.5
13.8 cm
Triangle = 3, Square = -1, Star = 5
Answer:
x = 3 and -2 are the two solutions.
Step-by-step explanation:
2x^2 -2x -12 = 0
First factor out a 2
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0
2 = 0 x - 3 = 0 x + 2 = 0
2 does not equal zero so this is an extraneous solution
x - 3 = 0 so x = 3
x + 2 = 0 so x = -2
To evaluate this, plug in the number 4 for the variable a and the number 5 for the variable 5.
6a + 3ab
6(4) + 3(4)(5)
To solve this multiply then add.
Multiply from left to right and don't add until everything has been multiplied.
Basically, 6(4) + 3(4)(5) = (6 • 4) + (3 • 4 • 5).
6 • 4 = 24
3 • 4 = 12
12 • 5 = 60
Now we have 24 + 60.
Just add and you have your answer!
24 + 60 = 84
So when a is 4 and b is 5, <span>6a + 3ab is equal to 84.
