Nutka1998 [239]3 years ago
8 0

Answer:

  • 72 square units

Step-by-step explanation:

Consider the figure as the difference of a trapezoid and a rectangle.

<u>Area of the trapezoid:</u>

  • a = 3 - (-2) = 5 units
  • b = 9 - (-6) = 15 units
  • h = 5 - (-5) = 10 units
  • A = (a + b)h/2 = (5 + 15)(10)/2 = 100 square units

<u>Area of the rectangle:</u>

  • l = 5 - (-2) = 7 units
  • w = -1 - (-5) = 4 units
  • A = lw = 4*7 = 28 square units

<u>Area of the figure:</u>

  • 100 - 28 = 72 square units

(-6,8); perpendicular to y = -3/2x -1
UNO [17]

Answer:

y =  \frac{2}{3} x + 12

Step-by-step explanation:

y =  -  \frac{3}{2} x - 1

The gradient of a line is the coefficient of x when the equation of the line is written in the form of y=mx+c.

Thus, gradient of given line=-  \frac{3}{2}.

The product of the gradients of perpendicular lines is -1.

(Gradient of line)(-3/2)= -1

Gradient of line

- 1 \div ( -  \frac{3}{2} ) \\  =  - 1( -  \frac{2}{3} )  \\  =  \frac{2}{3}

Substitute m=\frac{2}{3} into y=mx+c:

y =  \frac{2}{3} x + c

To find the value of c, substitute a pair of coordinates.

When x= -6, y= 8,

8 =  \frac{2}{3} ( - 6) + c \\  \\ 8 =  - 4 + c \\ c = 8 + 4 \\ c = 12

Thus, the equation of the line is y =  \frac{2}{3} x + 12.

(-2.9a + 6.8) + (4.4a - 7.3)
= -2.9a + 6.8 + 4.4a - 7.3
Combine like terms. All "a" terms can only be added to other "a" terms, and all non variable terms can only be added to other non variable terms.
= 1.5a - 0.5

Final Answer: D. 1.5a - 0.5

What’s a number that multiplies to four but adds to three
d1i1m1o1n [39]

Answer:

The answer is clearly 4 and 1. If we change the sign on 1 (making it -1), then you have the answer to your original question. 4 and -1 multiply to -4 and add up to 3.

The length of a rectangle is 24 more than its width. Find the area of the rectangle if its perimeter is 100 cm.
Serggg [28]

Answer:

481

Step-by-step explanation:

Lets say width = x

Length = x+24

Perimeter is 100 so

100=x+24+x+24+x+x

100=4x+48

100-48=4x

52=4x

x=13

So width = 13

Length = 37

37x13=481
