Not A because regular means all sides are equal.
B has to be the answer because the others are not.
Not C because a right triangle is not regular, i.e. and equilateral triangle.
Not D because a rectangle has different side lengths.
Answer:
-4 or -9
Step-by-step explanation:
-a^2-13a-36=0
(-a-4)(a+9)=0
-a-4=0
a+9=0
a= -4, -9
The first option is correct. For the following question, the simplified expression for the volume is 8x3 + 14x2 + 3x.
Answer:
48
Step-by-step explanation:
Using Uclid's division algorithm, the HCF of 960 and 432 can be obtained as follows:
Here, 960 is greater and 432 is smaller. We divide 960 by 432.
STEP 1:
960 = 432*2 + 96
STEP 2:
Divide divisor (432) by remainder (96)
432 = 96 * 4 + 48
STEP 3:
Divide divisor (96) by remainder (48)
96 = 48 * 2 + 0
Since, remainder at this step is zero (0), so the HCF would be the divisor of this step which is 48.
Thus, HCF of 960 and 432 is 48
P(Greece) =0.28 among tem P(G∩I) = 0.11. We also know tat
P(G ∪ I ) =1 [either Greece or Italy or both= all travelers)
The only data that is missing is te P(Italy)
P(G ∪ I ) = P(G) + P(I) - P(G∩ I)
1 =0.28 + P(I) so P(I) = 0.72
P(G) = 0.28 (including the 0 .11)
P(I) = 0.72 (including the 0.11)
P(G and I) =0.11
