Is the A
Step-by-step explanation:
Answer:
A. The height of the plant after week 3 was about 2.6 inches.
C. The height of the plant after week 9 was about 3.8 inches.
Step-by-step explanation:
The equation given:
Y = 0.2x + 2
x represents the number of weeks
substituting x = 3 into the equation , we will have
y = 0.2(3) + 2
y = 0.6 + 2
y = 2.6
This means that the height of the plant after week 3 was about 2.6 inches.
Also , substituting x = 9 into the equation will give
y = 0.2 (9) + 2
y = 1.8 + 2
y = 3.8
This means that the height of the plant after week 9 was about 3.8 inches.
16 of his stamps are from Africa, since 1/4 of 64 is 16. If I subtract his 28 from Europe and Africa (16 plus 12 equals 28) from his original 64, I am left with 36 stamps. 36/64 is simplified to 9/16. So 9/16 of Terrence's stamps are from Asia.
Since supplementary angles are angles that equal to 180, you first need to subtract 40 from 180 to find out what the equation equals. This is the layout of the equation. 140=4x+20. Next you subtract 20 from each side, 120=4x then you divide by 4 four, x=30.
Answer:
2·(a^2 + b^2) = (a + b)^2
2·a^2 + 2·b^2 = a^2 + 2·a·b + b^2
a^2 + b^2 = 2·a·b
a^2 - 2·a·b + b^2 = 0
(a - b)^2 = 0
a = b
