Answer:
27 + 36 = 63
A. (9 + 3)(9 + 4) = 12 × 13 = 156
B. 9(3 + 4) = 9 × 7 = 63
C. 9 + (3 × 4) = 9 + 12 = 21
D. (9 × 3)(9 × 4) = 27 + 36 = 63
Option B and D
1) 4√3 - 24√3 = -20√3
2) Multiply and simplify square root of 3 times the quantity of 4 + square root of 12:
(√3) x 4 + √12==> (√3) x 4 + √(4 x 3)==> 4√3 + 2√3 = 6√3
3) Simplify √3 + 4√3. ===> =5√3
Answer: 60 units²
Step-by-step explanation:
The total area of the rectangle is equal:
(4+4)*(9+3)=
8*12=
96 units²
The area of the unpainted part of the rectangle is equal:
4*9=
36 units²
The area of the shaded region is equal:
96-36=
60 units²
The graph is touching the x-axis at x = - 5 and is turning away. This means the multiplicity of the root is 2.
So the roots f the polynomial are x= - 5 and x =- 5. The factors of the polynomial are x - 5 and x - 5. The polynomial can be expressed as the product of its factors. So the given polynomial is (x + 5)(x + 5).
Thus, the correct answer is option D
