We can let the "a number" be represented by the variable x.
1) 7x
2) 7 + x
3) x - 7
4) 7 + 2x
Hope this helped and have a great day!

20 points! I would really like some help! :) (Question attached below)

snow_lady [41]

Answer:

See below.

Step-by-step explanation:

(a)

To multiply two polynomials, multiply every term of the first polynomial by every term of the second polynomial. Then combine like terms.

$(\dfrac{1}{2}x - \dfrac{1}{4})(5x^2 - 2x + 6) =$

$= \dfrac{1}{2}x \times 5x^2 - \dfrac{1}{2}x \times 2x + \dfrac{1}{2}x \times 6 - \dfrac{1}{4} \times 5x^2 + \dfrac{1}{4} \times 2x - \dfrac{1}{4} \times 6$

$= \dfrac{5}{2}x^3 - x^2 + 3x - \dfrac{5}{4}x^2 + \dfrac{1}{2}x - \dfrac{3}{2}$

$= \dfrac{5}{2}x^3 - \dfrac{9}{4}x^2 + \dfrac{7}{2}x - \dfrac{3}{2}$

(b)

No. Since the binomials are different, the product of two different binomials and the same trinomial will give different results.

PLZ HELP I NEED AN ANSWER NOW I WILL MARK BRAINLYEST

Vesnalui [34]

Answer:

Δ MNO ≅ ΔXYZ by AAS postulate.

Step-by-step explanation:

Given:

$\angle M=\angle X$ , $\angle N=\angle Y$ , and YO = NZ.

Consider YO = NZ

Add OZ on both sides

YO + OZ = NZ + OZ

YZ = NO

Consider triangles Δ MNO and ΔXYZ.

Statement Reason

1. $\angle M=\angle X$ Given

2. $\angle N=\angle Y$ Given

3. YZ = NO ∵ YO = NZ

Therefore, the two triangles Δ MNO and ΔXYZ are congruent to each other from AAS postulate as two corresponding angles and a corresponding side are equal to each other.
