Answer:
4x - 3
Step-by-step explanation:
(7x - 2) - (3x - 5)
Open the bracket and observe the signs,
7x -2 - 3x + 5 ( when the minus outside the bracket multiplies minus in the bracket, it becomes plus)
Collect like terms
7x - 3x - 2 + 5
4x - 3
Yes, because if two angles of a triangle are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°.
X = 2
A square has 4 sides. To get the perimeter of a square, you could multiply the length of one side by 4.
One side of the larger triangle is x inches plus an additional 8 inches, which can be written as (x+8)
To get the perimeter of the larger square, multiply the expression (x+8) by 4. The question states the larger square’s perimeter is 40 inches.
You end up with this equation: 4(x + 8) = 40
To solve first distribution 4 into (x + 8).
4x + 32 = 40 | subtract 32 from both sides
4x = 8 | divide each side by 4
x = 2 inches
So the side length of the original square is 2 inches. To check your work, go back and plug x = 2 into the original equation. 8 in + 2 in = 10 inches, and 10 inches x 4 = 40 inches, so x = 2 is the solution
Resolving a function of any nature means determining your zeros or raizes.
The zeros of a function occur when the function is null.
Then:
f(x) = 3x - 2
To determine the root
f(x) = 0 = 3x - 2
3x = 2
x = 2/3 Final result
Answer:
537.6
Step-by-step explanation:
0.93*x=500
x=500/0.93
x=537.6
