Hello there,
Well we are given with 3(x + 4)² and we need to simplify this expression...
- write out the expression: 3(x + 4)(x + 4)
- then we distribute the parentese: 3(x² +4x +4x +16)
- combine like terms: 3(x² + 8x + 16)
- distribute the 3 in the parentese: 3x² + 24x + 48
So another way to express this would be 3x² + 24x + 48.
Hope I helped,
Amna

Answer:
-2x^10
Step-by-step explanation:
-8x^7 x^3/4 - -8x^10/4
12 units squared
Step-by-step explanation:
You realize that the shape can be divided into 3 shapes;
2 right-angled triangles (one small and one bigger one) and a rectangle. We can find the area of each and then sum them up. Because we are finding area under the shape, the negative signs will be ignored;
Larger right-angled triangle;
½ b * h
½ * 4 * 4 = 8
Smaller right-angled Triangle;
½ * b * h
½ * 2 * 2 = 2
Rectangle;
L * W
2 * 1 = 2
Sum of all the areas;
2 + 2 + 8 = 12
= 12 units squared
