Base times height is the formula for area I’m pretty sure
Rewrite y^4 as (y^2)^2
(y^2)^2 + 14y^2 +49
Rewrite 49 as 7^2
(y^2)^2 + 14y^2 +7^2
Factor using the perfect square rule.
Final answer: (y^2 + 7)^2
Answer:
x=-3/19
y=39/19
Step-by-step explanation:
the equations can be written as the following system
If the second equation is multiplied by 3/2 it will become -18x+3y=9
If that equation is then subtracted with the first you will obtain the following
-19x=3, it means x=-3/19
The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19
Answer: Don’t know duidjdjdjdhdhd
Step-by-step explanation:
x+y=6 and 20x+30y=140 can be used to determine the number of each type of lawn mowed by Sarah.
Step-by-step explanation:
Given,
Charges for cutting small lawns =$20
Charges for cutting large lawns = $30
Total yards mowed = 6
Total amount earned = $140
According to given statement;
x+y=6 Eqn 1
20x+30y=140 Eqn 2
x+y=6 and 20x+30y=140 can be used to determine the number of each type of lawn mowed by Sarah.
