Answer:
Yes.
Step-by-step explanation:
Any number raised to the power of 2 will be greater than the original number.
A positive number:
4² = 16
A negative number:
-3² = 9
Or:
0² = 0
Answer:
7in, 7in, and 15 in
Step-by-step explanation:
Based on the Triangle Inequality Theorem that states that the sum of any 2 sides of a triangle must be greater than the measure of the third side, we can find what set of lengths cannot form a triangle.
The only set that does not follow the theorem is the set with lengths 7in, 7in, and 15in. It does not follow the theorem because...
7 + 7 < 15 (which should not be true based on the theorem)
Answer:
3
Step-by-step explanation:
Answer:
x = 45
Step-by-step explanation:
(2x + 6)/3 = (5x - 1)/7
<em>Cross multiply</em>
7(2x + 6) = 3(5x - 1)
<em>Expand both expressions</em>
14x + 42 = 15x - 3
<em>Collect like terms</em>
42 + 3 = 15x - 14x
45 = x
x= 45
<em>Check:</em>
7(2*45 + 6) = 3(5*45 - 1)
7(90 + 6) = 3(225 - 1)
7 * 96 = 3 * 224
672 = 672
