Answer:
9m^2 + 18m + 9
Step-by-step explanation:
(3m + 3)2
Square ;
(a + b)^2 = a2 + b2 + 2ab
(3m + 3)2
= (3m)^2 + (3)^2 + 2 (3m)(3)
= 9m^2 + 9 + 18m
= 9m^2 + 18m + 9
Answer:
whats the question
Step-by-step explanation:
Answer:
The correct option is;
The ratio of the area of the scale drawing to the area of the sign is equal to the square of the scale factor
Step-by-step explanation:
Here we have a scale factor of 1:8
Therefore area of drawing = 1/2×base, b×height, h = 1/2×b×h
Hence, the area of the triangular sin will be given by 1/2×8×b×8×h
Area of triangular sign = 64 × 1/2×b×h
Hence the ratio of the area of the scale drawing to the area of the triangular sign is equal to the square of the scale factor.
Your answer would be x = 1.
The rules for a kite shape is that two pairs are of equal length, which means we can say that AD = CD and thus form an equation:
3x + 4 = x + 6
- x
2x + 4 = 6
- 4
2x = 2
÷ 2
x = 1
