Answer:
2500
Step-by-step explanation:
a² + 2ab + b²
49² + 98 + 1
Comparing terms
a²= 49²
a= 49
2ab = 98
2× 49 × b = 98
98b = 98
b= 98/98
b = 1
or
b²= 1
b=√1
b= 1
a=49 and b= 1
Hence (a+b)²= (49+1)²
50²= 2500
Answer:
Y = - 2/3 x + 3
Step-by-step explanation:
y = -2/3x+5/3
Slope = -2/3. .. parallel line has same slope
For (- 3 , 5)
Y intercept = y - my = 5 - ( (-2/3) x (-3) ) = 3
Y = slope x X + y intercept
Y = - 2/3 x + 3
Answer:
1/2 or 1:2
Step-by-step explanation:
3 circles to 6 squares
3/6 simplified is 1/2
An athletic director pays $90 for 12 sun visors for the
softball team. The rate per sun visor is equal to $90 / 12 sun visor = $ 7.5
per sun visor. So the athletic director should pay ($ 7.5 per sun visor)*(15
sun visor) = $ 112.5
