Answer:
The total length of Valerie’s walls is (2.5 × 4) + (21.25 × 3) + 32.
The total length of Seth’s walls is 3.5 + (22.75 × 2) + 58.
To find the expression for the perimeter of the house, add Valerie’s expression to Seth’s:
(2.5 × 4) + (21.25 × 3) + 32 + 3.5 + (22.75 × 2) + 58.
Step-by-step explanation:
its the platho answer so change it a bit
X is the number
sum means add
sum of half a number and 4 means
(x/2)+4
result is -16
(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40
The first and the third equation can be solved by using the zero product property. Let us examine each equation.
4x²+16x=0
4x(x+4)=0
4x=0 and x+4=0
where x1=0 and x2=-4
Next answer is whown below:
(x+4)(x-12)=0
x1=-4 and x2=12
Therefore, the first and the third equations are the answers.
I’ll teach you how to solve 3x-5=-18
—————————————-
3x-5=-18
Move constant to the right-hand side and change its sign:
3x=-18+5
Calculate the sum:
3x=-13
Divide both sides of the equation by 3:
X=-13/3
Your Answer Is x=-13/3
Plz mark me as brainliest if this helped :)
