Answer:
87.6
Step-by-step explanation:
Answer:
1.8 x
Step-by-step explanation:
The expression is [3x10^6][6x10^8}
]
Step 1: Multiply the coefficients 3 and 6, we get 18.
Step 2: If we have the same base, we add the powers.
So 10^6 *10^8 = 10^(6 + 8) =
Step 3: Now combine 18 and
= 18 x
The coefficient must be less than 10, in 18, we have one 10, we can move that to the exponent and 18 = 1.8 *10
Step 4: When we simplify, we get 1.8 x
Hope you will understand the steps.
Thank you.
Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
