Make two formulas-

A=2xy
120=16xy

If 16xy = 120 then 2xy will equal 120/8 which equals 15.

A= 15cm cubed

V_B=2x\cdot2y\cdot4=16xy=120\ cm^3\\
V_A=x\cdot y\cdot2=2xy\\\\
16xy=120\ cm^3\\
2xy=15\ cm^3=V_A

Find the variable x in the figure if AB ll CD ll EF where c and d are the midpoints of AE and BF.
dangina [55]
CD is called the middle base and is equal to :(AB + EF)/2

CD = <span>(AB + EF)/2

4x = [(x</span>²+10) + (8-x)]/2

8x = x²+10+8-x

8x= x²-x+18
x²-9x+18 = 0

x' = [-b+√(b²-4.a.c)]/2a       & x" = [-b-√(b<span>²-4.a.c)]/2a

x'= 6  and x" = 3, So we have2 values of x</span>

In triangle ABC above, AD is perpendicular to CB. If the lengths of AD and CB were both increased by 50%, how would the area of
astra-53 [7]

Answer:

The answer is below

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene triangle, equilateral triangle, isosceles triangle.

The area of a triangle is given as:

A = (1/2) * b * h

where b = base of triangle, h = height of triangle , A = area

Let BC = base = x, and AD = height = y, hence:

A = (1/2) * x * y = 0.5xy

If the lengths of AD and CB were both increased by 50%, hence:

new AD = y + 0.5y = 1.5y, new CB = x + 0.5x = 1.5x

The new area= (1/2) * 1.5y * 1.5x = 1.125xy

Increased area / area = 1.125xy / 0.5xy = 2.25

If the lengths are increased by 50%, the area would also increase and the new area would be 2.25 times
