Answer:

Step-by-step explanation:

The answer is B. Shape A is a square which all the sides are the same length. This mean it has 2 pairs of parallel sides. Shape B is a rectangle which also has 2 pairs of parallel sides. Shape C is rhombus which also has 2 pairs of parallel sides. Shape D is a trapezoid which only has 1 pair of parallel sides.

Answer:

Step-by-step explanation:

the second one is correct. the first one is wrong because shape C also has those angles. the third one is wrong because shape C also has no perpendicular sides. the fourth one is wrong because shape C also has 2 pairs of angles with the same measure.

How do i put this in slope-intercept form. passes through 2,-2 and 4,-1

enot [183]

Answer:

$\large\boxed{y=\dfrac{1}{2}x-3}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (2, -2) and (4, -1).

Substitute:

$m=\dfrac{-1-(-2)}{4-2}=\dfrac{-1+2}{2}=\dfrac{1}{2}$

Put the value of a slope and the coordinates of the point (2, -2) to the equation of a line:

$-2=\dfrac{1}{2}(2)+b$

$-2=1+b$ subtract 1 from both sides

$-3=b\to b=-3$

Finally:

$y=\dfrac{1}{2}x-3$

Factor the expression 20g3 + 24g2 – 15g – 18

abruzzese [7]

First, put parenthesis around the first two numbers and the last two numbers.
(20g³+24g²) (-15g-18)
Then, take out the greatest common factor of both parenthesis.
4g²(5g+6)-3(5g+6)
You then separate the numbers outside the parenthesis and the numbers in the parenthesis.
(5g+6) (4g²-3)
Then you simplify the second set of numbers. Since the set of numbers can't be simplified, you would leave this problem as it is. I hope this makes sense.

FIND AREA OF SHADED SEGMENT. WILL GIVE BRAINLIEST FOR CORRECT ANSWER

Xelga [282]

By geometry,
$area \: of \: shaded \: region \: = (\: area \: of \: square \: - \: 2 \times (area \: of \: semi - circles)) \div 2$
$= ({l}^{2} - 2 \times \pi \times {r}^{2} ) \div 2$
$l = 6 \\ r = l \div 2 = 3$
$= (36 - \pi \times {3}^{2} ) \div 2$
$= 3.86$
area of shaded region = 3.9

How do I solve 4[2.5 + 3 (20 + 7)] ?

DerKrebs [107]

$4[2.5+3(20+7)]=4[2.5+3 \cdot 27]=4[2.5+81]=4 \cdot 83.5=334$
