Answer:

16.5 square feet

Step-by-step explanation:

The logo consists of

rectangle with sides of 3 ft and 1.5 ft;
trapezoid with bases 3 ft, 4 ft and height of 3 ft;
triangle with base of 1.5 ft and height of 2 ft.

The area of rectangle:

$A_{rectangle}=1.5\ ft\times 3\ ft=4.5\ ft^2$

The area of trapezoid:

$A_{trapezoid}=\dfrac{3\ ft+4\ ft}{2}\times 3 \ ft=3.5\ ft\times 3 \ ft=10.5 \ ft^2$

The area of triangle:

$A_{triangle}=\dfrac{1}{2}\times 1.5\ ft\times 2 \ ft=1.5\ ft^2$

Hence, the area of logo:

$A=A_{rectangle}+A_{trapezoid}+A_{triangle}=4.5\ ft^2+10.5\ ft^2+1.5\ ft^2=16.5\ ft^2$

Answer:

$-7+5[(-5)^2+(-32)]=-42$

Step-by-step explanation:

First solve the sums that are within the parentheses.

Remember that if the numbers have equal signs then they are added and the same sign is placed.

If the numbers have different signs they are subtracted and the sign of the major is placed

So:

$-3-2=-5$

$2^3 -40 = 8-40=-32$

Then we have the following expression:

$-7+5[(-5)^2+(-32)]$

Remember that by multiplying signs you get:

(+) * (+) = +

(-) * (-) = +

(+) * (-) = -

(-) * (+) = -

Then:

$-7+5[(-5)^2+(-32)]=-7+5[(-5)*(-5) -32]$

$-7+5[(-5)^2+(-32)]=-7+5[25 -32]$

$-7+5[(-5)^2+(-32)]=-7+5[-7]$

$-7+5[(-5)^2+(-32)]=-7-35$

$-7+5[(-5)^2+(-32)]=-42$
