Hello
So values of x which is not in this domain is
which is [-7,0]
hope this helps
Isosceles Right
Isosceles, since the two side lengths are equal, and it is a right triangle since it has a 90 degree angle and two other 45 degree angles.
We can automatically rule out both Right and Equilateral Triangles, this is because there is no 90 degree angle (Needed for a right triangle) and all three angles are not equal (needed for an equilateral triangle).
Looking a little deeper, we know that an isosceles triangle has two congruent (or same) angles. Meaning we can rule this one out as well.
This leaves option A) Scalene Triangle
And to check, we think about a scalene triangle, and we know it's a triangle that has 3 unequal sides, meaning that this could qualify!
Answer:
158 in²
Step-by-step explanation:
<u>Surface area</u>
A = 2·(l·w + l·h + w·h)
= 2·(3in·8in + 8in·5in + 3in·5in)
= 2·(24in² + 40in² + 15in²)
= 2·(79in²)
= 158 in²
