For rhombus A:
base = 7 in
area = 35 in²
Area of rhombus = b * h
⇒ 35 = 7 * h
⇒ h = 35/7
⇒ h = 5 in
Rhombus B:
height = 3*5 = 15 in
base = 7*3 = 21 in
Area = 15 * 21 = 315 in²
Area
of rhombus B is 9 times area of rhombus A. When the dimensions are
increased to 3 times the initial dimension, area became 9 times.
Answer: (n + 5)(n - 5)
Explanation: In this problem, we have a binomial that's the difference of two squares because n² and 25 are both perfect squares and we are subtracting or taking the difference of these two squares.
Since the difference of two squares factors as the product of two binomials, we can setup our parenthses and in the first position, we use the factors of n² that are the same which are n · n.
In the second position, we use +5 and -5 as our factors of -25.
So our answer is (n + 5)(n - 5).

Answer:
Defending the inference and challenge
Step-by-step explanation:
The inference is correct no one chosen math. Most of them choose english, few of them choose history, and only two choose science.
There are 1000 7th grader, since they did not ask them what was their favorite subject. They could of had 65% for math, 25% for english, 5% for science and history. We do not know.
Hopes this help
This really depends on the fraction; if there are variables in the equation, if they are full numbers,etc. I'd really recommend looking up khan academy on YouTube and that will really help you out!
