Step-by-step explanation:
area of the full rectangle is 96 sqcm (12x8) and then you subtract the area of the cutout (4x4)
Answer:
The correct option is A.
Step-by-step explanation:
The given graph sh a shows scatter plot and linear model of Joanna's height, in inches, for various ages.
From the given graph it is noticed that the linear line passing through the points (0,30) and (2,35).
The slope of the linear model is

The slope of linear model is 2.5, it means the Joanna can expect her height to increase about 2.5 inches every year.
Therefore option A is correct.
Answer:
3x + 18
General Formulas and Concepts:
<u>Pre-Alg</u>
Step-by-step explanation:
<u>Step 1: Define expression</u>
3(x + 6)
<u>Step 2: Expand</u>
- Distribute 3 to both terms: 3x + 18
We use the BODMAS method to solve the given questions.
Solve the Bracket then Divide Multiply Add and Subtract
1. 32÷4×(16×1/2) - 2
= 32÷4 × ( 8 ) - 2
= 8 × 8 - 2 = 64 - 2 = 62
2. 20 ÷ (5×2/5) + 3
= 20 ÷ (2) + 3 = 20 ÷ 2 + 3
= 10 + 3 = 13
3. 1/2 ×(6×4) ÷ 3 + 2
= 1/2 × 24 ÷ 3 + 2
= 1/2 × 8 + 2
= 4 + 2 = 6
4. 2 (6÷2+8) - 4
= 2 (3+8) - 4
= 2 × 11 - 4
= 22 - 4
= 18
