Answer:
B
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 9² = 15²
x² + 81 = 225 ( subtract 81 from both sides )
x² = 144 ( take the square root of both sides )
x = = 12 → B
Answer:
16n2−10n+22
Step-by-step explanation:
J=justin
marcella=m
aimee=a
j is 2 older than 1/3 of m
'of' means multiply
j=2+1/3m
a is 4 younger than 2 times j
a=-4+2j
represent justin's age?
dunno
ok so I can solve if I know m=63
j=2+1/3m
j=2+1/3(63)
j=2+21
j=23
subsitute
a=-4+2j
a=-4+2(23)
a=-4+46
a=42
justin is 23 and aimee is 42 if marcella is 63
Answer:
Step-by-step explanation:
