Answer:

A, D, and F

Step-by-step explanation:

Tiara did multiply and regroup correctly in the first partial product. Tiara did not multiply and regroup correctly in the second partial product. Tiara was not correct when she added her 2 partial products.

Tiara should of got 18,291 but instead she got 16,291.

When she went to the part to multiply 3x4 she didn't add the remaining 2 from the 3x6+2. So if she did 3x4+2 she would of got the number 14 instead of 12 to put down in the second partial product. Which would make the addition part of it as 4,221 + 14070 = 8291 instead of 4,221 + 12,071 = 16, 291

I hope you understand :)

Answer:

$5\sqrt{18}-\sqrt{32} \\=5 \sqrt{3 \times 3 \times 2} - \sqrt{2 \times 2 \times 2 \times 2 \times 2} \\ = 5 \times 3 \times \sqrt{2} - 2 \times 2 \times \sqrt{2} \\ = 15 \sqrt{2} - 4 \sqrt{2} \\ = \boxed{11 \sqrt{2} }$

<h3>11√2 is the right answer.</h3>

22x^3 y^4+28x^2 y^5+34xy^4

Leya [2.2K]

Answer:

2xy4 • (11x2 + 14xy + 17)

Step-by-step explanation:

(((22•(x3))•(y4))+((28•(x2))•(y5)))+(2•17xy4)

(((22•(x3))•(y4))+((22•7x2)•y5))+(2•17xy4)

(((2•11x3) • y4) + (22•7x2y5)) + (2•17xy4)

5.1 Pull out like factors :

22x3y4 + 28x2y5 + 34xy4 = 2xy4 • (11x2 + 14xy + 17)

Trying to factor a multi variable polynomial :

5.2 Factoring 11x2 + 14xy + 17

Final result :

2xy4 • (11x2 + 14xy + 17)

How do you solve 14p−8=22+20p ?

Zanzabum

The value of p is -5

Simply use cross multiplication :

The process of multiplying numbers in the shape of a fraction is called cross multiplication. Cross multiplying, also known as cross multiplication, is the process of multiplying the numerator of one fraction by the denominator of the other fraction on the other side of an equal symbol. Cross multiplication is a method for comparing fractions.

Both fractions with like and unlike parts are multiplied across. When employing the cross-multiplication procedure, we multiply the denominators as well as the numerators when a fraction is dissimilar, or when the denominators of two fractions are not alike.

$14p-8=22+20p\\or, 14p-20p=22+8\\or, -6p=30\\or, p=-\frac{30}{6} \\or, p= -5$
