Answer:
D=(3x-2)
Step-by-step explanation:
Area=length×width =3x²+7x-6
thus a=3 b=7 c=-6
W=(x+3)
since c is -6 it has to be the product of 3(from W)=-2
since a=3 multiply by x (from W) 3×x=3x
=3x-2
check if its correct.
3x-2×x+3
x(3x-2)+3(3x-2)
3x²-2x+9x-6
3x²+7x-6 thus its true
Answer:
the answer is b on oddesseyware
Step-by-step explanation:
Answer:
1.
Statement: m∠A + m∠B + m∠C = <u>180°</u>
Reason: <u>Sum of Angles in a Triangle</u>
2.
Statement: 28° + x - 4° + <u>2x</u> = 180°
Reason: Substitution
3.
Statement: x = <u>52°</u>
Reason: Algebra
Answer:
x + y = 180
and,
x = 3y
Step-by-step explanation:
Data provided in the question:
Total area of the farm = 180 acre
x represents the acre in which corn is planted
y represents the acre in which wheat is planted
Thus,
Area of corn + Area of wheat = Total area of farm
x + y = 180 ................. (1)
also,
From the statement, farmer wants to plant three times as many acres of corn as wheat
we can conclude
Area of corn = 3 times the area of wheat
or
x = 3y ................(2)
So, we have system of linear equations that represent the situation as
x + y = 180
and,
x = 3y
