You would need to add 7x to both sides.

Answer:

Option a) Adding 7x to both the sides

Step-by-step explanation:

Given is an equation linear in one variable x.

-7x -5= x + 3

To solve this equation we have to bring x terms on one side and constants on the other side.

Subtracting 5 from both sides will not eliminate the constant -5 hence wrong.

Adding x to both sides will make right side as 2x instead of eliminating x.

Combining like terms will give -7x-x not -7x+x hence incorrect

Adding 7x to both sides gets rid of x term on the left.

Hence this option is right answer

Which polynomial equation of least degree has -2, -2, 3, and 3 as four of its roots? (x + 2)(x - 3) = 0 (x - 2)-2(x + 3)3 = 0 (x
azamat

Answer:

(x + 2)²(x - 3)² = 0

Step-by-step explanation:

Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0

Could these triangles be congruent?
Mama L [17]

Answer:

yes, if AB ≅ DE

Step-by-step explanation:

Triangles are said to be congruent if they have the same sides and the same angles.

The following measures are used to determine if triangles are congruent:

1) Angle-side-angle: If two angles and a side of a triangle is equal to two angles and corresponding side of another triangle, then they are congruent.

2) Side-side-side: If all three sides of a triangle is equal to three sides of another triangle, then the two triangles are congruent.

3) Side angle side: If two sides and an included angle of a triangle is equal to the two sides and corresponding angle of another triangle, then they are congruent.

4) Hypotenuse - leg: If the hypotenuse and one leg of a triangle is equal to the hypotenuse and leg of another triangle then they are congruent.

From the triangles  DEF and ABC, already, they already have one equal triangle that is ∠F = ∠B and an equal side i.e DF = AC.

To satisfy congruence, two sides and an angle have to be equal, therefore if AB = DE then the two triangles would be congruent
