20
Step-by-step explanation:
x+8x=180
9x=180
x=20
Three ways to correctly compare the following numbers are, 352 = 352, anything else is impossible with < and >
Answer:
96 ft
Step-by-step explanation:
Perimeter= a (base)+b (side)+c (side)
281 = 89 +b + c
281 -89 = b + c
192 = b+ c ( however in an iscoceles triangle, 2 sides aree equal therefore b and c will be equal)
So: 192/2 = 96
To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.
