5x + 2 = 6x + 11   Subtract 6x frlom both sides
 -x + 2 = 11           Subtract 2 from both sides
       -x = 9            Divide both sides by -1
        x = -9

X=-9
subtract 6x from both sides to get x alone as -1x, subtract 2 from both sides to balance. -1x=9, or 1x=-9

The area A of a triangle with base b and height h is given by A = = bh. Find the area when b = 18 m (meters) and h = 30 m.
Pie

Answer:

Area = 270m^2

Step-by-step explanation:

Given

A = \frac{1}{2}bh

b = 18m

h = 30m

Required

Solve for A

Simply substitute 18 for b and 30 for h

A = \frac{1}{2}bh

A = \frac{1}{2} * 18 * 30

A = 270

Hence:

The area is

Area = 270m^2

Which of the following expressions represents the area of a trapezoid with bases of 3x and 5x and a height of 6x?
BaLLatris [955]
Trapezoid Area = (Base1 + Base2) (h/2)
so A = (3x + 5x )(6x/2)= 24x^2

ABC and ACD are both right angled triangles. a) explain why the length of AC is 13cm.​
timofeeve [1]

Answer:

In the picture attached, the question is shown.

a) Applying Pythagorean theorem to triangle ABC, and solving for AC:

CB² + BA² = AC²

5² + 12² = AC²

√169 = AC

13 cm = AC

b) Applying Pythagorean theorem to triangle ACD, and solving for AD:

CD² + AC² = AD²

5² + 13² = AD²

√194 = AD

13.9 cm = AD
