You know that two expressions are equivalent when if you substitute in your values and simply the expressions, they have the same answer.
If you used $8, then you must add 8 to 32 which equals $40
Simple interest formula:
I=PRT
I(interest money created in dollars)
P(initial amount of money)
R(interest rate as a decimal)
T(time in years)
I=7000(.07)(6)
I=$2,940
Therefore, the future value of A is $2,940
IF IT EQUALS 0
1. find two number that multiplied to 48 and adds to 14, which are 6 and 8.
2. substitute the new numbers in with x to get x^2 + 6x + 8x + 48.
3. factor out the x and the 8 to get x(x+6)+8(x+6).
4. x = -6, x = -8
IF IT DOES NOT EQUAL 0
then (x+6)*(x+8) is your answer.
Answer:
A=32
Step-by-step explanation:
Area of a trapezium=1/2(a+b)h
A=1/2(6+10)4
A=1/2(16)4
divide 16 by 2
A=(8)4
open the bracket
A=32
Check/ verify
A=1/2(a+b)h
32=1/2(6+10)4
32=1/2(16)4
divide 16 by 2
32=(8)4
32=32.
I hope this hopes?
