The answer is A
A Parallelogram is a shape with 4 sides that has two pairs of parallel sides. The opposite sides must have equal length. This is accurate for this shape.
A Rectangle is a shape with 4 sides that has four right angles. This is accurate for this shape.
A rhombus is a shape with 4 sides of equal length. This is not accurate for this shape.
A square is a shape with 4 sides of equal length and four right angles. This is not accurate for this shape.
X - y = 7.....x = y + 7
x * y = 60
y(y + 7) = 60
y^2 + 7y = 60
y^2 + 7y - 60 = 0
(y + 12)(y - 5) = 0
y + 12 = 0
y = -12....not this one because it is negative
y - 5 = 0
y = 5 <===
x - y = 7
x - 5 = 7
x = 7 + 5
x = 12 <==
so ur 2 numbers are 12 and 5
Answer:
x = 200
Step-by-step explanation:
Given
x - 
y = 30 ← substitute y = 15 into the equation
x - × 15 = 30 , that is
x - 10 = 30 ( add 10 to both sides )
x = 40 ( multiply both sides by 5 to clear the fraction )
x = 200
