Where The Picture. ? Or Whole Problem
Answer:
the top one is $12.
Step-by-step explanation:
simple: 48÷4=12 because 4×10=40.
4×2=8. 40+8=48 which is the amount of money it costs, so add the 2 factors that aren't 4 to get your answer. (division is similar to reverse multiplication)
Let L and W be the length and width of the given rectangle, respectively. Perimeter is calculated through the equation,
P = 2L + 2W
Substituting the perimeter,
36 = 2L + 2W
Simplifying,
18 = L + W
The area is calculated by multiplying the length and width as below,
A = 80 = LW
Substituting the expressions,
80 = (L)(18 - L)
The value of L from the equation is 8. With this, the value of W is equal to 10.
Therefore, the dimensions of the rectangle are 8 m by 10 m.
-2(2b-3)
Multiply the bracket by -2
Whenever multiplying a -negative number with a -negative number= + positive number.
(-2)(2b)(-2)(-3)
-4b+6
Answer: -4b+6
