(((3(4))+7)(7)) is the answer
Answer: It would be 170
Step-by-step explanation:
5 x 10 + 5 x 10 + 5 x 10 = 150 but since it is park of the rectangle and not the triangle you don't multiply by 1/2 but the triangle part 4 x 5 you do 4 x 5 x 1/2 with is ten then you do it for the other side 4 x 5 x 1/2 equals ten. So 150 + 10 + 10=170
Answer:
linear. :)
Step-by-step explanation:
Answer:
1) -5 and +5; 2) -9 and +9
Step-by-step explanation:
1) a² + 2ab + b² = 25
(a + b)² = 25 Wrote the left-hand side as a square
a + b = ±5 Took the square root of each side
All values of a + b are -5 and +5.
2) a² − 8ab + 16b² = 81
(a - 4b)² = 81 Wrote the left-hand side as a square
a - 4b = ±9 Took the square root of each side
All values of a - 4b are -9 and +9.
Y=7-2×(-5/2)
Y=7+5
Y=12
The answer is C
