Answer:

The total value of the given expression is 12.

Step-by-step explanation:

(-2 + 1)² + 5(12 ÷ 3) - 9

First, do the expressions within the parentheses.

(-1)² + 5(4) - 9

Next, simplify the exponents.

1 + 5(4) - 9

Next, multiply 5 by 4.

1 + 20 - 9

Add 1 and 20 together.

21 - 9

Subtract 9 from 21.

So, the final answer to this equation is 12.

The terminal tower in cleveland ohio is 239 ft shorter than key tower also in cleveland the total heights of the two buildings i

Nutka1998 [239]

T + k = 1655
k = t + 239

now we sub
t + t + 239 = 1655
2t + 239 = 1655
2t = 1655 - 239
2t = 1416
t = 1416/2
t = 708 ft <== terminal tower

k = t + 239
k = 708 + 239
k = 947 ft <=== key tower
