Answer:
x=8 and y=2
Step-by-step explanation:
Use the sine law: sinB/b = sinA/a
SinB = b*sinA/a
sinB = 3*sin120° /8
∠ B = 18.94° ≈ 19°
Answer:
The answer to your question is: (2a + 2b)²
Step-by-step explanation:
a² + b² = z
ab = y
Which is equivalent to 4z + 8y ?
Substitution
4(a² + b²) + 8(ab)
Simplify 4a² + 4b² + 8ab
Order 4a² + 8ab + 4b² It's a perfect square trynomial
Factorize (2a + 2b)²
Answer:
D
Step-by-step explanation:
(3, 9) (-3, 5)
0 is in the middle 7 is in the middle
for x: 3 2 1 0 -1 -2 -3 for y: 9 8 7 6 5
Thus, (0, 7) is the midpoint between (3, 9) and (-3, 5)
Answer:
He drove 111 miles
If we were given the distance Lan drove last weekend instead off how much gas he used then we would have to find the amount of gas used by lan.
Step-by-step explanation:
Ian's car can go 185 miles on 5 gallons of gas
On 5 gallons of gas lan's car can go 185 miles
Therefore in gallon of gas lan 's car can go
185/5 = 37
So, for 3 gallons of gas lan's car can go
3 × 37 = 111
for 3 gallons of gas lan's car can go 111 miles
If we were given the distance Lan drove last weekend instead off how much gas he used then we would have to find the amount of gas used by lan.
