Triple the dimensions, multiply, and you get D
Answer:
In bold.
Step-by-step explanation:
a. (x+5)^2 – 3x(x+5) x+5 is common
= (x + 5)(x + 5 - 3x)
= (x + 5)(5 - 2x)
b. (x + 5)(5 - 2x) = 0
x = -5, 2.5.
2a. Area of the square = (x + 5)^2
Area of triangle AEB
= 1/2 * base * height
I am assuming that H is the centre of AB , so
Area = x*x
= x^2.
2b
6x^2 = (x + 5)^2
6x^2 = x^2 + 10x + 25
5x^2 - 10x - 25 = 0
x^2 - 2x - 5 = 0
x = [-(-2) +/- sqrt(2^2 - 4*1*-5)] / 2
x = -1.45, 3.45.
(we ignore the negative).
<span>a) It is prime - 2, 3
b) It is odd number and less than 5 - 1, 3,
c) It is an even number - 2,4
d) It is 3
If a) and c) is true, then Number is 2. 2 is prime and 2 is even.
b) and c) is false.</span>
Answer:
Exponential decay
Step-by-step explanation:
Because the values are exponentially decreasing.
