Answer:

312cm2

Step-by-step explanation:

Area of the triangles:

A =1/2bh

A=1/2(10*12) = 1/2*120=60.

There are two triangles. 60*2=120. 120 is the area of both triangles.

Area of the rectangle:

16*12=192.

Diego’s current age is five times Martina’s age ten years ago. If Martina is currently m years old, what is Diego’s current age
puteri [66]

Answer:

5m-50

Step-by-step explanation:

Let Diego current age be x,

Given that Diego’s current age is five times Martina’s age ten years ago

Martina current age = m years

10 years ago Martina's age = m-10

Hence we have

x = 5(m-10) = 5m-50

So we find that Diego's current age can be expressed in terms of m as

Deigo's current age= 5m-50

Verify:

Deigo current age = 5m-50

Hence Martina age 10 years ago = 5m-50 divided by 5 = m-10

Martina current age = m-10+10 = m

Verified.

What is the equation of a parallel line to y = -5x + 2 that passes through the point (-1, 4)?
Luden [163]

Answer:

The equation of the Parallel line passes through the point (-1,4) is

y = -5 x -1

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given the equation of the line y = -5 x + 2

Given point (-1 , 4 )

The equation of the parallel line of a given line is 5x + y +k=0 ...(i)

The equation (i) passes through the point (-1,4)

                 5(-1)+4+k=0

                -5 +4 +k =0

                    -1 + k = 0

                         k = 1

<em>The equation of the Parallel line passes through the point (-1,4) is </em>

<em>    y = -5 x -1</em>
