Answer:
4 cannot be the measure of the third side. This is because of the Triangle Inequality Theorem, which states that the sum of two sides of a triangle must be greater than the third side (A+B>C, A+C>B, B+C>A) In this example, if side C were 4, side C (4) plus side A (8) would be 12. Since side B is 12, and 12 cannot be greater than 12, 4 would not work.
Answer=8
Step-by-step explanation:
Answer:
72.22
Step-by-step explanation:
Literally just add up the coins and their value
Answer:
i) 7x + 8 = -90
<=> 7x = -98
<=> x = -98/7
<=> x = -14
ii) 5y - 4 = 2y - 25
<=>3y = -21
<=> y = -21/3
<=> y = -7
iii) 4(p + 3) = 36
<=> p + 3 = 36/4
<=> p + 3 = 9
<=> p = 9 - 3
<=> p = 6
iv) 2 (4f + 3) = 3 (2f + 6)
<=> 8f + 6 = 6f + 18
<=> 2f = 12
<=> f = 12/2
<=> f =6
Hope this helps!
