Let the height of the triangle be x then the base becomes as 4+x
now area of triangle in a plane surface is given by
1/2*base*height
thus
1/2*(4+x)*x= 16
4x+x^2 = 32
x^2 +4x -32 = 0
x^2+8x-4x-32
x(x+8)-4(x+8)
therefore x is equal to -8 or +4
hence it can't be in negative so it is +4
thus base becomes +8
the height is 4 cm and base is 8cm

Answer:

In Step 4, the inequality sign should be flipped.

Step-by-step explanation:

Whenever you multiply or divide both sides of an inequality by a negative number, you need to flip the inequality sign. So, in Step 4, when you divide both sides by -10, the sign should be flipped.

The final answer should be:

\frac{-27}{10} \geq x

Gerry plans to place a 29 foot ladder against the side of his house to clean his gutters. The bottom of the ladder will be 3 fee
tensa zangetsu [6.8K]

Answer:

8\sqrt{13}

Step-by-step explanation:

Using the pythagorean theorem (Assuming the house's walls are perpindicular to the ground):

a^2+b^2=c^2

we can find that 3=a and 29=c

3^2+b^2=29^2

9+b^2=841

b^2=832

b=\sqrt{832}

b=\sqrt{64*13}

b=8\sqrt{13}

That is the height that the ladder will reach
