Answer:
B) 1 < x < 13
Step-by-step explanation:
use triangle inequality theorem which states that the sum of any two sides must be greater than the third side
let x = third side
6 + 7 > x; x < 13
6 + x > 7; x > 1
x + 7 > 6; x > -1
there will always be one inequality which produces a negative value which you can exclude from your answer because a length cannot be negative
The answer is 8
First divide, then square root to get rid of the squared.
Substitute -3 for x in f(x) = 2x^2 + 4x + 10:
f(-3) = 2(-3)^2 + 4(-3) + 10 = 18 - 12 + 10 = 16 (answer)
Step-by-step explanation:
Isosceles means that two sides are equal.
if the base is 1½s the other two sides will be ½s and½s
thus perimeter=1½+½+½ =2½s
<u>s</u><u>m</u><u>a</u><u>l</u><u>l</u><u>e</u><u>r</u><u> </u><u>t</u><u>r</u><u>i</u><u>a</u><u>n</u><u>g</u><u>l</u><u>e</u><u>:</u>
perimeter=½(1½s+½s+½s)
=½(2½s)
=1¼s convert to decimal
=1.75s
So the 45-45-90 triangle is considered a special triangle. If the legs are x, then the hypotenuse is x√2.
In this case, since the hypotenuse is 4√2, the legs are C. 4 units.
