Answer:
x - 5
Step-by-step explanation:
The fourth or the D) Option is correct.
To find the new induced matrix via a scalar quantified multiplication we have to multiply the scalar quantity with each element surrounded and provided in a composed (In this case) 3×3 or three times three matrix comprising 3 columns and 3 rows for each element which is having a valued numerical in each and every position.
Multiply the scalar quantity with each element with respect to its row and column positioning that is,
Row × Column. So;
(1 × 1) × 7, (2 × 1) × 7, (3 × 1) × 7, (1 × 2) × 7, (2 × 2) × 7, (3 × 2) × 7, (1 × 3) × 7, (2 × 3) × 7 and (3 × 3) × 7. This will provide the final answer, that is, the D) Option.

Answer:
3/5
Step-by-step explanation:
(18-2X)(8-2X)
Take each side and subtract 2X, then multiply them together for the area.
The ski jacket costs $160 and the pants cost $70 because if u do 160-20=140 which, if u divid by 2, will give you 70
The answer is $230
