Answer:

x = 27

Step-by-step explanation:

Given

3x - 4y = 65 ← substitute y = 4 into the equation

3x - 4(4) = 65

3x - 16 = 65 (add 16 to both sides )

3x = 81 ( divide both sides by 3 )

x = 27

3(x^2+4x)+4(y^2-2y)=32
nekit [7.7K]

Answer:

3x^2 + 12x + 4y^2 - 8y = 32

Step-by-step explanation:

3(x^2+4x)+4(y^2-2y)=32

At first we have to break the parenthesis to get the variables in normal position. To break those, we have to multiply each with the help of algebraic expression:

or, (3*x^2) + (3 × 4x) + (4 × y^2) - (4 × 2y) = 32

or, 3x^2 + 12x + 4y^2 - 8y = 32

Since the equation does not have anything to add or deduct, therefore, it is the answer.

A rectangle has a volume of 912 cubic meters. It has a length of 19 meters and a width of 12 meters. Which equation can be used
Nimfa-mama [501]
The answer would be B because LWH=V, so taking the information given, L(19) times W(12) would equal 228 and 228 times the H would give us volume so B
Hope this helped ;)
