Answer:

  • 2 - 4 + 6*8 = 46

Step-by-step explanation:

<u>There are 6 possible options:</u>

  • 2 - 4 + 6*8 = 46
  • 2 - 4*6 + 8 = - 14
  • 2 + 4 - 6*8 = - 42
  • 2 + 4*6 - 8 = 18
  • 2*4 - 6 + 8 = 10
  • 2*4 + 6 - 8 = 6

As we the highest possible number is 46

Answer:

2*4*6*8

Step-by-step explanation:

384 is the answer.

Notice that if you do minus or plus, you get a smaller number. So, this is indeed the highest number John could obtain.

Answer:

\large\boxed{A=153\ cm^2}

Step-by-step explanation:

<em>Look at the picture.</em>

We have

square with side length a = 9

trapezoid with base lengths b₁ = 9 and b₂ = 6 and the height length h = 6

right triangle with legs lengths l₁ = 3 + 6 = 9 and l₂ = 6

The formula of an area of a square

A=a^2

Substitute:

A_I=9^2=81\ cm^2

The formula of an area of a trapezoid:

A=\dfrac{b_1+b_2}{2}\cdot h

Substitute:

A_{II}=\dfrac{9+6}{2}\cdot6=\dfrac{15}{2\!\!\!\!\diagup_1}\cdot6\!\!\!\!\diagup^3=(15)(3)=45\ cm^2

The formula of an area of a right triangle:

A=\dfrac{l_1l_2}{2}

Substitute:

A_{III}=\dfrac{(9)(6)}{2}=\dfrac{54}{2}=27\ cm^2

The area of the shape:

A=A_I+A_{II}+A_{III}\\\\A=81+45+27=153\ cm^2
