80X3 PLUS 2x3 that is awnser
Answer:
120
Step-by-step explanation:
6 x 6 = 36
6 x 7 = 42
42/2 = 21
21 x 4 = 84
84 + 36 = 120
We know that
[area old square]=x*x--------> x²
[area new square]=(x+6)*(x+6)-------> (x+6)²-----> A=x²+12x+36
the answer is
An <span>expression to represent the area of the new square is (</span>x²+12x+36)
Answer:
14 miles.
Step-by-step explanation:
Let the distance traveled from home to destination = x miles.
Speed while going to friend's house = 35 miles per hour.
Speed while coming back = 40 miles per hour.
Total Time taken for the journey = 45 minutes = 0.75 hours.
Let the time taken while going to friend's house = y hours.
Therefore, the time taken while going to friend's house = (0.75 - y) hours.
To find x and y, model the speeds of both the journeys.
Speed while going to friend's house = Distance/Time.
35 = x/y.
x = 35y (Equation 1).
Speed while coming back = Distance/Time.
40 = x/(0.75 - y).
x = 40(0.75 - y) (Equation 2).
Since x = x, therefore:
35y = 30 - 40y.
75y = 30.
y = 30/75.
y = 0.4 hours.
Put y = 0.4 hours in Equation 1:
x = 35y.
x = 35(0.4).
x = 14.
Therefore, the distance between my friend's house and my house is 14 miles!!!
