Answer:

16

Step-by-step explanation:

Dividing 2 fractions is the same as multiplying the fraction in the numerator with the inverse of the fraction in the denominator.

Therefore,

$\frac{-20}{3}$ ÷ $\frac{-5}{12}$
$-\frac{20}{3}$ × $-\frac{12}{5}$
Note : -ve signs cancel out, cross multiply 20 and 5 to get 4, and cross multiply 12 and 3 to get 4
⇒ 4 x 4
⇒ 16

Hi,

AxB = 0 means A=0. or B=0

so 2 solutions :

4x-3= 0

4x=3

x = 3/4

and x+2 = 0.

x= -2

solutions are : -2 +and 3/4

Which of these expressions CANNOT be simplified by combining like terms?

densk [106]

$5ab^{3} +7-3a^{2} b ^{2} +a^{3}b+10$ can be simplified to by adding the 7 and 10 to get $a^{3}b-3a^{2} b ^{2}+ 5ab^{3} + 17$ .

$5ab^{3}+3a^{2}b^{2}+a^{3}b -10$ cannot be simplified any more by combining like terms.

By distributing the 2b into the parentheses, you can simplify the expression:
$5ab^{3}+2b(3ab^{2})+a^{3}b-10\\
5ab^{3}+6ab^{3}+a^{3}b-10\\
11ab^{3}+a^{3}b-10$

Here you can just add:
$5a^{3}b^{3}+3a^{2}b^{2}+a^{3}b^{3}-10ab\\
6a^{3}b^{3}+3a^{2}b^{2}-10ab$

Thus, the only expression that cannot simplify any more using adding like terms is the second, $5ab^{3}+3a^{2}b^{2}+a^{3}b -10$ .

Find the slope of the line that passes through the points (-4, 7) and (3,-2)

schepotkina [342]

Answer:

-9/7

Step-by-step

Slope Formula:

$\frac{y_2-y_1}{x_2-x_1}$

We can plug in the numbers 7 and -2 for the y and -4 and 3 for x

$\frac{7-(-2)}{-4-3} =\frac{9}{-7}$

An isosceles trapezoid is a quadrilateral with two congruent legs and a pair of parallel bases. Prove the base angles of an isos

Finger [1]

When the sides are congruent (same direction and size), and the two opposite sides are parallel, the angles are the same. In an isosceles triangle, two angles are congruent, because two sides are congruent.
