4 because you take 2²= 2 times 2 = 4
Answer:
thxs
Step-by-step explanation:
X + y = 12
x - y = 4
-----------------add
2x = 16
x = 8
x - y = 4
8 - y = 4
y = 4
answer
two numbers: 8 and 4
doule check
sum = 8 + 4 = 12
difference = 8 - 4 = 4
The value of x that makes sense in this context is; 32.
The dimensions of the new garden is; 64 by 16.
<h3>How to find the real dimensions of the rectangle?</h3>
The expression that represents the problem statement is;
x² = (2x)(x – 16)
Expanding the bracket gives us;
x² = 2x² – 32x
x² - 32x = 0
x(x - 32) = 0
Thus; x = 0 or x = 32
x can't be 0 and as such the value of x is 32.
Thus;
The length of the new garden is; l = 2x = 64.
The width of the new garden is; w = x - 16 = 32 - 16 = 16
The dimensions of the new garden are therefore; 64 by 16
