198+727=925 round it to 930.
Answer:
x = 9
Step-by-step explanation:
Since you have a equilateral triangle all angles are 60°.
7x - 3 = 60
7x = 60+3
7x = 63
x = 63/7
x = 9
What do they mean by describe the diagram
To solve this problem you must apply the proccedure shown below:
1. You have the following quadratic equation, which is given in the problem above:
<span>2y^2+6y-8=0
2. So, to solve it, you can use the quadratic formula, which is:
y=(-b</span><span>±</span>√(b²-4ac))/2a
<span>
a=2
b=6
c=-8
3. When you susbtitute these values into the formula, you obtain:
y1=-4
y2=1</span>
