Answer:

(x - 7)(x - 3)

Step-by-step explanation:

Given

x² - 10x + 21

Consider the factors of the constant term (+ 21) which sum to give the coefficient of the x- term (- 10)

The factors are - 7 and - 3 , since

- 7 × - 3 = + 21 and - 7 - 3 = - 10, thus

x² - 10x + 21 = (x - 7)(x - 3) ← in factored form

Answer:

Step-by-step explanation:

x^2-10x+21

(x-7)(x-3)

find the 2 numbers that when multiplied make the last number or +21 and when combined make the middle number of -10. -7*-3 = 21 and -7+-3=10

1. Simply. Show your work.

$9$ · $5+4$ Simplify The Exponents

$45+4$ Multiply $9$ to $5$

$49$ Add $45$ to $4$

*(Answer)*= $49$

2. Model and Solve.

$4$ ÷ $\frac{2}{3}=?$ Use the KCF strategy

$4$ ÷ $\frac{2}{3}=?$ K = Keep the whole number or freaction on the left

$4$ · $\frac{2}{3}=?$ C = Change the division sign to multiply sign

$4$ · $\frac{3}{2}=?$ F = Flip the fraction or whole number

$\frac{4}{1}$ · $\frac{3}{2}=?$ Make $4$ into a fraction

$\frac{12}{2}$ Multiply the numerator to another and the denominator to another

$6$ Divide 12 to 2 to simplify the fraction

*(Answer)*= $6$

3. Based on the diagram, describe how a parallelogram and rectangle are related.

They are the same is because the rectangle is the same as the parallelogram because it is same shade, however, sightly tilted.

4. Solve.

- $\frac{5}{8}$ · $\frac{1}{2}= \frac{5}{16}$

- $\frac{1}{4}$ · $\frac{4}{5}=\frac{4}{20}=\frac{1}{5}$

If you want than I can edit the answer to add Thursdays answer

Hope this helps

6x - y^2 +3x; if x = 4, y = 7, z = 10

uysha [10]

Answer:

Step-by-step explanation:

x = 4

y = 7

z = 10

6x - y^2 + 3z

= 6 ( 4 ) - 7^2 + 3 ( 10 )

= 24 - 49 + 30

= 24 + 30 - 49

= 54 - 49

= 5
