Answer:
A) 2cm
Step-by-step explanation:
According to the Triangle Inequality Theorem, the sum of the measure of any two sides of a triangle MUST be larger than the measure of the third side. In this case, with sides 3cm and 5cm, the third side would have to be at least 3cm in order for the smallest two sides to be larger than the third side:
3cm + 3cm = 6 cm > 5cm
However, if the third side was only 2cm, then the two smaller sides would be 5cm, which is only equal to and not larger than the third side:
3cm + 2cm = 5cm
Any other measurements larger than 3cm, when added to the given side of 3cm, would be larger than 5cm and would form a triangle. So, the only measure that would NOT form a triangle would be 2cm.
Answer:
12 units²
Step-by-step explanation:
The two are congruent, so C'D' is still 6units long. L*W = 6 * 2 = 12 units^2
Axis of symmetry -3 and -8 or 3 and -8
Diagonals that bisect each other are perpendicular and form a right angle.
AEB is a right triangle.
We can apply the Pythagorean theorem:
c^2 = a^2+b^2
Where c is the hypotenuse (longest side) and a and b the other 2 legs.
Replacing:
AB^2 = AE^2+BE^2
AB^2 = 5^2+12^2
AB^2 = 25+144
AB^2 = 169
AB=√169 = 13
Lenght of AB= 13

Answer:
Ben's
Step-by-step explanation:
If E is the amount of energy that each full set of panels produces, then ...
3 of Ismael's 5 panels produce 3/5E
4 of Ben's 6 panels produce 4/6E
We can compare these fractions when they have a common denominator.
3/5E = 18/30E . . . . energy from Ismael's panels
4/6E = 20/30E . . . energy from Ben's panels
18/30 < 20/30 . . . . so Ben's panels are producing more energy
