Answer:
(x+4)(x+4)
Step-by-step explanation:
The middle number is 8 and the last number is 16. Factoring means we want something like (x+_)(x+_). We need two numbers that add together to get 8 and multiply together to get 16. The number 4 works perfectly in this equation. That's why (x+4)(x+4) is the factor of the equation x^2 + 8x + 16.
From the question, we know that:
a = 56
l = 8
w = n - 3
To find the number (n), we should find the width (w) first
General formula of rectangle area is
l × w = a
Input the number to the formula
l × w = a
8w = 56
w = 56/8
w = 7
After finding the width, we find n
w = n - 3
n - 3 = w
n - 3 = 7
n = 10
The number is 10
Answer:
X=12
Step-by-step explanation:
simplify both sides of the equation then isolate the variable.
5/2(12)-7=23
3/4(12)+14=23
making both equations equal to each other.
Answer:
357.46 meters squared
Step-by-step explanation:
16 x 12.2 x 1/2 = 97.6
12.2 x 10.6 = 64.66
97.6 x 3 = 292.8
292.8 + 64.66 = 357.46
