Answer:

Prime: x^2 + 17x - 30.

Difference of 2 squares: 256x^4 - 49x^2.

GCF: 4x^2 - 24x + 144.

Perfect Square trinomial: 4a^6 - 28a^3 + 49

Factoring Trinomial: b^2 + 5b - 36.

Step-by-step explanation:

1. x^2 + 17x - 30 will not factor.

2. 256x^4 - 49x^2 = (16x^2 + 7x)(16x^2 - 7x)

3. 4x^2 - 24x + 144 = 4(x^2 - 6x + 36).

4. 4a^6 - 28a^3 + 49 = (2a^3 - 7)^2.

5. b^2 + 5b - 36 = (b + 9)(b - 4).

Please help urgent!!

USPshnik [31]

Answer:

$Q M \cong R M \Rightarrow$ definition of midpoint

$\overline{P M} \cong \overline{P M} \Rightarrow$ Reflexive property of congruence

$\Delta P Q M \cong \Delta P R M \Rightarrow$ SSS congruence postulate

$\angle Q \cong \angle R \Rightarrow$ CPCTC theorem

Step-by-step explanation:

Step 1: Since, M is the midpoint of the line segment QR.

$\overline{Q M} \cong \overline{R M} \Rightarrow$ definition of midpoint

Step 2: The reflexive property of congruence states that a line segment or an angle or a shape is always equal to itself.

$\overline{P M} \cong \overline{P M} \Rightarrow$ Reflexive property of congruence.

Step 3: The SSS congruence postulate states that if three sides of a triangle are equal to three sides of another triangle, then the two triangles are congruent.

$\Delta P Q M \cong \Delta P R M \Rightarrow$ SSS congruence postulate

Step 4: CPCTC theorem states if two triangles are congruent then the sides and angles are also congruent.

$\angle Q \cong \angle R \Rightarrow$ CPCTC theorem.

Someone please help me !

Answer:

Can't tell if it went through...

1. Shop A = 2x

2. Shop B = 2x - 580

3. Total = Shop A + Shop B

1949 = 2x + 2x - 580

4. Combine like terms

2x + 2x = 4x

1949 = 4x - 580

5. Add 580 to both sides (to remove -580 from right side)

1949 + 580 = 4x - 580 + 580

2529 = 4x

6. Divide both sides by 4 (to get x)

2529 / 4 = 4x / 4

632.25 = x

7. Shop A = 2x

2 * 632.25 = 1264.50

Shop A = 1264.50

8. Shop B = 2x - 580

2 * 632.25 - 580 = 684.50

Shop B = 684.50

Check: Shop A + Shop B = 1949

1264.50 + 684.50 = 1949

Shop A = 1264.50

Shop B = 684.50
