H the equation has x = 4 and x = -4 as it’s only solutions is true
Answer: As a fraction, the answer is 3/8 (because 5/8 - 2/8 = 3/8). As a whole number, 3/8ths can be represented by 0.375 (as 0.375 is equal to 3/8). :)
Step-by-step explanation:
Let the two numbers be X and Y respectively.
<u>We know that</u> :
(a) X = 6Y + 5
(b) X + Y = 75
7Y + 5 = 75
X = 65
Y = 10
The dimensions are 8 ft x 8 ft.
The total area is 64 sq ft.
The dimensions of a single tile are 2 1/2 x 1 1/2
X/10 = 10/4x
4x^2 = 100
x^2 = 25
x = 5
answer
5 units
