9:60 is one hours
it takes 15 mins to get to 60
47-15=32
9:45+47=9:45+15:32=10:00+32=10:32 AM
Answer:
Step-by-step explanation:
(16.2t+3.4u+2.9)cm
Step-by-step explanation:
A triangle is a plane shape that has three sides. The perimeter of a triangle is gotten by taking the sum of all the lengths of the three sides. Let the length of the three sides by s1, s2 and s3, the perimeter of the triangle will be expressed as;
P = s1+s2+s3
Given the side lengths
s1 = (8.1t-6.1)cm
s2 = (8.1t+7.1)cm
s3 = (3.4u+1.9)cm
Perimeter of the triangle = 8.1t-6.1+8.1t+7.1+3.4u+1.9
collect the like terms
P = 8.1t+8.1t+3.4u-6.1+7.1+1.9
P = 16.2t+3.4u+2.9
Hence the expression that represents the perimeter, in centimeters, of the triangle is (16.2t+3.4u+2.9)cm
Solution:
2(6+7)= 3(5+2)
Step ; 1 { Solving first Term i.e LHS }
LHS : 2 ( 6 + 7)
☞ 2 ( 13)
☞ 2 × 13
☞ 26
Now, RHS ; 3 ( 5 + 2)
☞ 3 ( 7)
☞ 21
From Equation 1 and 2, We can LHS and RHS are not Equal.
Therefore, 26≠ 21.
