5(2z + 4) = 0
10z + 20 = 0
10z = -20
z = -20/10
z = -2
This is algebra. 4 times whatever is in the parentheses (8x-8) has to be equal to -192. If you do the math, x= -7
Acute-The angle is less than 90 degrees
Equilateral-All sides are equal in length
Isosceles-Two of the sides are equal in length
Scalene-None of the sides are equal in length
Right-The angle is 90 degrees
Obtuse-The angle is greater than 90 degrees
We can see that none of the sides are the same length, so we know that it must be scalene. We can also see that every angle is less than 90 degrees, so we know that is must be acute.
The triangle is scalene and acute.
Hope this helps!!
Answer:
$18 per ft²
Step-by-step explanation:
x = cost of 1 squared foot of sheet metal
Just do some subtraction
7.6x - 3.5x = 73.8
4.1x = 73.8
Divide both sides by 4.1
4.1x/4.1 = 73.8/4.1
x = 18
