Answer:
the square rug will cover 0.33 square feet more
Step-by-step explanation:
The area of a rectangle is the product of its length and width. The area of the rectangular rug is ...
(4.8 ft)(8.2 ft) = 39.36 ft^2
Similarly, the area of the square rug is ...
(6.3 ft)(6.3 ft) = 39.69 ft^2
The square rug has the larger area by ...
39.69 -39.36 = 0.33 . . . square feet
(x + 2)²<span> + 12(x + 2) – 14 = 0
</span>(x +2) ² we use the formula (a+b)² = a² + 2ab + b²
<span>
(x</span>² + 2*2*x + 4 ) + (12*x + 12 * 2 ) - 14 = 0
(x² + 4x + 4) + (12x + 24) - 14 = 0
x² + 4x + 4 + 12x + 24 - 14 = 0
<span>we sort expressions
</span>x² + 4x + 12x + 4 + 24 - 14 = 0
<span>reduce
</span>x² + 16x + 14 = 0
a = 1 b = 16 c=14
Δ = b² - 4ac = 16² - 4*1*14 = 256 - 56 = 200
√Δ = √(2*10*10) = 10√2
Answer A
Answer:
Y=-4/5x+3/5y
Step-by-step explanation: first get the gradient
3--1/-3-2
=4/-5
y-3/x+3=4/-5
-5y+15=4x+12
-5y=4x-3
y=4/-5x+3/5
