Since 36x² + 60x + 25 is the perfect square trinomial, we use this formula a² + 2ab + b² = (a + b)². Hence, the solution is (6x + 5)²
Answer: Choice C
The pink equation is y = 2x-3
The yellow equation is y = -2x+1
Notice how the pink equation crosses the y axis at (0,-3) or at -3 on the y number line. This tells us that the pink equation has a y intercept of -3. So b = -3
This only happens with the equation y = 2x-3. The other equations do not have a y intercept of -3. So this quickly rules out the other choices leaving C as the only answer.
An alternative is to find two points on the pink line, such as (0,-3) and (1,-1). Then find the slope of the line through those points. You should find the slope to be m = 2. So m = 2 and b = -3 leads to y = 2x-3. Follow similar steps for the yellow line as well.
Multiplication is always the same. A huge help is using a calculator. In year 3 you work on times tables, I think. If you have trouble with a specific question please elaborate.
