1: Write as a sum
x^2+7x+10
2: Factor the expressions
x^2+5x+2x+10
3: Factor the expression

Answer:
40cm and
80cm
Step-by-step explanation:
Given
Sides = 10cm
Perimeter of the first square = 4a
= 4 x 10 = 40cm
For the second square, the sides are increased by 2 times
So 2 x 10 = 20cm
Therefore,
Perimeter = 4 x 20 = 80cm
The perimeter of the second square is twice that of the first square
The answer is D. In the function
, A value of 5 would make the denominator 0. This is undefined, so 5 is excluded.
Without seeing the graph, it's impossible to tell. The same can be said if we don't know the function rule. However, we can rule out three non-answers.
Choice B is false because the interval [1,3] has f(x) below zero but the rest of the interval to the right of x = 3 has f(x) not below zero.
Choice C is false. The value x = -1 leads to f(x) = 0 which is not greater than 0
Choice D is false because the values 8 and 4 are positive
After eliminating B, C, & D, we are left with choice A as the answer.
Answer:
n = 72
Step-by-step explanation:
