Answer: No triangles can be formed.
Step-by-step explanation: Given Dimensions = 15cm , 7cm , 5cm
Inequality property = Sum of 2 shorter sides ≥ 3rd side
∴ 7 + 5 is not greater than 15
∴<u><em> No triangles can be formed.</em></u>
<u><em /></u>
The discriminant is b^2-4ac
ax^2+bx+c=0
x^2+11x-10=0
11^2-4(1)(-10)
1. Simplify 11^2 to 121
121-4(1)(-10)
2. Simplify 4*1*-10 to -40
121-(-40)
3. Simplify brackets
121+40
4. Simplify
161
Your discriminant is 161
Answer:
x=140/-18
x=-7+7/9
Step-by-step explanation:
-5(4x-2)+2x+1=151
We move all terms to the left:
-5(4x-2)+2x+1-(151)=0
<em>We add all the numbers together, and all the variables</em>
2x-5(4x-2)-150=0
<em>We multiply parentheses</em>
2x-20x+10-150=0
<em>We add all the numbers together, and all the variables</em>
-18x-140=0
<em>We move all terms containing x to the left, all other terms to the right</em>
-18x=140
x=140/-18
x=-7+7/9
16 Feet
it is a pythagreon triple of 6 8 10
so double that and you have 12 16 20
