3^2 - (5 x 2^3) HELP PLEASE I need step by step

Leto [7]

Answer:

$-31$

Step-by-step explanation:

We need to find the value of: $3^2 - (5 * 2^3)$ .

First we need to look at the BIDMAS rule.

B - Brackets

I - Indices

D - Division

M - Multiplication

A - Addition

S - Subtraction

First we need to work out what is in the brackets which is: $(5 * 2^3)$

We look at the next rule which is Indices so we do $2^3$ first.

$2^3 = 2 * 2 * 2 = 8$

Then we multiply it by the five which gets us:

$(5 * 8) =40$

Now that we've finished with what is inside the brackets, we can work out what's outside which is:

$3^2 = 3 * 3 = 9$ .

Now we've simplified it down to:

$9 - (40)$

Which gets us:

$9 - 40 = -31$

You design the wooden picture frame and paint the front surface.

Hitman42 [59]

Answer:

a) 8x + 28
b) 68 in²

Step-by-step explanation:

Area of the frame with picture:

A = lw
A₁ = (x + 4)(x + 7) = x² + 11x + 28

Area of the picture:

A₂ = x(x + 3) = x² + 3x

Area of the wooden frame is the difference of the above values:

A₃ = A₁ - A₂
A₃ = x² + 11x + 28 - x² - 3x
= 8x + 28

When x = 5, the picture frame area is:

A₃ = 8*5 + 28 = 40 + 28 = 68 in²
