Answer:
it is A hope this helps:)
Let
x--------> <span>represents the length of a single tile
L-------> t</span><span>he length of the floor
W------> the</span><span> width of the floor
A--------> </span>area of a tiled kitchen floor
<span>
we know that
A=W*L
A=</span>4x²<span> + 24x + 27
</span>so
W*L=4x² + 24x + 27---------> equation 1
L=2x+9------> equation 2
substitute equation 2 in equation 1
W*[2x+9]=4x² + 24x + 27
W=[4x² + 24x + 27]/[2x+9]
therefore
the answer is
the <span>expression that represents the width of the kitchen in terms of x is
</span>W=[4x² + 24x + 27]/[2x+9]
Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 2 ← is in slope- intercept form
with slope m = - 3
Answer:
=$2739.81
Step-by-step explanation:
To find the total amount if the interest is compounded, we use the compound interest formula.
A=P(1+R/100)ⁿ
A is the amount, P- principal, is the invested amount R is the % interest rate, n is the number if periods.
If compounded semi-annually, it means we have two periods in 1 year
The rate is also divided by 2
Thus 25 years have (25×2) = 50 periods.
A= 750(1+5.25/200)⁵⁰
=750(1.02625)⁵⁰
=$2739.81
