Answer:
speack engliush please
Step-by-step explanation:
Read as: x is to 1/4 as 32 is to 3/4
x / (1/4) = 32/(3/4)
4x = 128/3
x = (32)/3
C^2 is GCF for Part A
= c^2(3x^2 + 2x - 1)
= c^2(3x - 1)(x + 1)
Part B
x^2 - 2x + 1
= x^2 - x - x + 1
= x(x - 1) - 1(x - 1)
= (x - 1)^2
Part c
x^2 - 64
= (x + 8)(x - 8)
Answer:
$118.25
Step-by-step explanation:
Always convert the percentage to a decimal by moving the decimal two points to the right/dividing by 100. So 7.5 % = 0.075
110 x 0.075 = 8.25 (the amount of tax added)
110 + 8.25 = 118.25
You can also multiply 110 by 1.075, where the "1" is the $110 and the ".075" is the tax, and save the step of adding. 110 x 1.075 = 118.25
Answer:
33 inches
Step-by-step explanation:
In a quadrilateral ABCD, AB ∥ DC and AD ∥ BC.
AC = 20 in, BD = 20 in, AB = 13 in.
We want to find the perimeter of ΔCOD if point O is the intersection of the diagonals.
Since AB ∥ DC and AD ∥ BC, the point O divides the diagonals into two equal parts.
|OD|=|BD|/2 = 20/2 =10inch
Similarly,
|OC|=|AC|/2 = 20/2 =10inch
Also,
AB=CD=13 inch
Therefore,
Perimeter of ΔCOD= |OD|+|OC|+|CD|
=10+10+13
=33 inches
