Number 7 is C, im not sure about 6 though
-1/4 is bigger than -5/4
the closer the negative numbers are to zero, the larger they are, in this case the numerator is the same 4
Answer:
perimeter: 22x-14
area : 24x^2-37x
Step-by-step explanation:
for perimeter, it is the length of all the sides added together
starting at the left and working clockwise
5x+((6x-7)-(3x+1))+2x+(3x+1)+(5x-2x)+(6x-7)
5x+6x-7-3x-1+2x+3x+1+5x-2x+6x-7
combine like terms
perimeter: 22x-14
for area, area of (5x*(6x-7)) and subrtact the missing portion of (2x*(3x+1))
(30x^2-35x)-(6x^2+2x)
area : 24x^2-37x
Answer:
The measure of m∠KNY is;
(D) 105°
Step-by-step explanation:
From the diagram, we have;
The given angle at the circumference = The The angle the arcs makes at the center of the circle
From circle, theorem, angle subtended at the center = Twice the angle subtended at the circumference
Therefore;
Angle ∠D and angle ∠Y = 90°/2 = 45°
Angle ∠O and angle ∠K = 60°/2 = 30°
From angle summation theorem, we have;
m∠KNY + ∠K + ∠Y = 180° (The sum of the interion angles in ΔYNK
∴ m∠KNY = 180° - (∠K + ∠Y)
Plugging in the known values of ∠K and ∠Y gives;
m∠KNY = 180° - (30° + 45°) = 105°
m∠KNY = 105°.
2a) $6 off ... you multiply 0.20 by 30, and get 6
2b) $24 ... since discount is $6 off, you subtract $6 from the original price, $30, and get $24
