Ok so 1inch=40cm
2 inches by 1.5
multiply everybody by 40 and make them all centimeters
20*2=80
1.5*40=60
80cm by 60cm
1inch=2.54cm
find how many inches in 1 cm
divide both sides by 2.54
1/2.54inch=1cm
80 by 60 cm
multiply that by 1/2.54 nd find inches iquivlent
80 times 1/2.54=31.4960629921259842519685037008
60 times 1/2.54=23.622047...
ok so
dimentions is 31.4960629921259842519685037008 inches by 23.622047 inches
Answer:
4
Step-by-step explanation:
BCD is a right triangle. The Pythagorean Theorem applies; a^2 + b^2 = c^2, with c being the hypotenuse. a^2 + 9 = 25, so a^2 = 16, so a = 4

<span>y=4 (x-2)^2-1
y = 4(x^2 - 4x + 4) -1
y = 4x^2 - 16x + 16 - 1
y = 4x^2 - 16x + 15
