Answer: 70 square units
Step-by-step explanation:
Area of kite = (one diagonal * another diagonal) / 2
10 * 14 = 140
140 / 2 = 70
Answer:
Step-by-step explanation:
c.
y= 30x² +44x +16
factor
y= 2 (15x² +22x +8)
find zeros
15x²+22x+8=0
ax²+bx+c=0
x= (-b±√(b²-4ac))/2a
x= -22±√484-480/30 = -22±2/30 = -11±1/15
there are 2 zeros x= -10/15 ; x= -12/15
d.
y= 10x² +60x +80
factor
y= 10(x²+6x+8) = 10( x+2)(x+4)
finding zeros
x+2 =0 so x= -2
x+4 =0 so x= -4
there are 2 zeros x= -2; x= -4
The answer to this equation is 1.6
Answer:
Step-by-step explanation:
You divide the price with 9.25.
For example, if I wanted to buy a pouch(3.00) and pens(4.59), and the total without tax was 7.59 (add the prices), the tax would be 0.70 because 7.59/9.25=0.70. If I add 0.70 to 7.59, I would have to pay 8.29.
Hope this helps!
