-3+4x=5 x equals 5 because -3+4=1 and 1*5=5
Answer
greater than $1.
Step-by-step explanation:
the price of apples per pound is $1.37, therefore, the price per pound of apples is greater than $1.
V² + 3v - 5 = 0
v = -(3) ± √((3)² - 4(1)(-5))
2(1)
v = -3 ± √(9 + 20)
2
v = -3 ± √(29)
2
v = -3 ± 5.38
2
v = -1.5 ± 2.69
v = -1.5 + 2.69 or v = -1.5 - 2.69
v = 1.19 or v = -3.19
Let's be a and b the sides of the rectangle.
1 Area is 1600 =a*b
2. Perimeter is 2(a+b)=160 ==>b=80-a
So,
1600=a*b=a*(80-a)==>80a-a²=1600
==> a²-80a+1600=0
==> (a-40)²=0
==>a=40 or a=-40 (to exclude since <0)
==>b=1600/40=40
The rectangle is a square of 40m of side.
