S is located at (9 -3) point T is located at (4 -3)
cupoosta [38]

Answer:

5

Step-by-step explanation:

The distance formula is:

d = \sqrt {\left( {x_2 - x_1} \right)^2 + \left( {y_2 - y_1} \right)^2 }

We can plug in the given coordinates into the equation:

d = \sqrt {\left( {4 - 9} \right)^2 + \left( {-3 - (-3)} \right)^2 }\\d = \sqrt {\left( {-5} \right)^2 + \left( {-3+3} \right)^2 }\\d = \sqrt{25 + \left( {0} \right)^2 }\\d=\sqrt{25+0}\\d=\sqrt{25}\\d=5

If a rectangle is (x+2) wide and (x-7) in length, the area of the rectangle is? ​
Maru [420]

Answer: x² - 5x - 14

Step-by-step explanation: Start with the formula for the area of a rectangle.

Area = length x width

To multiply these two binomials, let's use the F.O.I.L. method.

The product of the first terms is x².

The product of the outer terms is -7x.

The product of the inner terms is 2x.

The product of the last terms is -14.

So we have x² - 7x + 2x - 14 which simplifies to x² - 5x - 14.

This is as far as I got can you check my work so far and tell me where to go from here
umka21 [38]
You did a simple mistake by forgetting to add 4 to itself in the square root. (-4^2=16)

x=(4 +/- sqrt(16-8))/4
x=(4 +/- sqrt(8))/4

Is this enough to get you started again?

Which statements about the factors of the terms in the expression 20a+15ab+24b are true?
nata0808 [166]
<span>1) Expression given: 20a+15ab+24b
</span>

2) Greates common factor GFC:

i) Coefficients:

20 = 2² × 5 × 1

15 = 3 × 5 × 1

24 = 2³ × 8 × 1


GCF = common numbers raised to the lower power = 1.
<span /><span /><span />

ii) Letters:
a
ab
b
Since, none letter is in the three terms, then there is not common letter as GFC.

iii) Conclusion the GCF is 1.


<span> 3) Let's see every option of the list:
</span><span>
</span><span>
</span><span>i) The factors common to 20a and 15ab are 1, 5, a, and b.
</span>

FALSE: becasue b is not in 20a.


<span /><span /><span> ii) The factors common to 20a and 15ab are 1, 5, and a.
</span>

TRUE: 1, 5, and a are in contained in both terms.
<span /><span /><span>
</span><span>iii) The factors common to 15ab and 24b are 1, 3, a, and b.
</span>

FALSE: a is not in 24b

<span /><span /><span> iv) The factors common to 15ab and 24b are 1, 3, and b.
</span>

TRUE: 1, 3, and b are contained in both terms.

<span /><span /><span> v) The factors common to 20a and 24b are 1, 2, 4, a, and b.
</span>

FALSE: a is not in 24b and b is not in 20a.
<span /><span /><span>
</span><span>vi) The factors common to 20a and 24b are 1, 2, and 4.
</span>

TRUE: 1, 2, and 4 are contained in both terms.

<span /><span /><span> vii) The GCF of the expression is ab.
</span>

FALSE: as seen above ab is not a common factor.

<span /><span /><span> viii) The GCF of the expression is 1
</span>

TRUE: it was proved above.
