Answer:
x=4.5 y=18.75
Step-by-step explanation:
solve using pythagorean theorem :
hypothenus²=opposite²+adjacent²
for y:
y²=15²+11.25²
y²=225+126.5625
y²=351.5625
y=18.75
for x:
7.5²=6²+x²
x²=7.5²-6²
x²= 56.25-36
x²=20.25
x=4.5
12 dimes and 48 nickles is the correct answer to the problem
Answer:
kinda hard
Step-by-step explanation:
Answer:
x = 0 or x = 3
Step-by-step explanation:
if f(x) = g(x) then – x2 + 4x + 1 = x + 1
add the like terms
-x^2 +3x = 0
-x (x-3) = 0 then x is either 0 or 3
