Answer:

  28 square units

Step-by-step explanation:

The figure can be decomposed several ways. Maybe easiest to see is as a 8×4 rectangle with a 2×4 right triangle cut from the corner.

The area of the rectangle is ...

  A = LW = (8)(4) = 32

The area of the missing triangle is ...

  A = 1/2bh = 1/2(2)(4) = 4

Then the area of the shaded figure is ...

  32 - 4 = 28 . . . square units

_____

Alternate solution

If you divide the figure with a horizontal line across the middle, it becomes a 4×4 square and a trapezoid with bases 2 and 4 and height 4. The shaded area is the sum of these areas.

The area of a trapezoid is ...

  A = 1/2(b1 +b2)h

  A = (1/2)(2 +4)(4) = 12

The area of the square is ...

  A = s² = 4² = 16

Then the total area is ...

  12 +16 = 28 . . . square units

Answer:

P = 54

Step-by-step explanation:

I personally separate the two rectangles that are visible. The first rectangle is 9ft in length and 6ft in width. Second rectangle is 9 feet in width and 3 feet in height. (I got 9 by subtracting 6 from 15).

P=2(l+w)

Put the numbers in according to the formula,

~1st Rectangle~

P = 2(9+6)

P = 2(15)

P =30

~2nd Rectangle~

P = 2(3+9)

P= 2(12)

P=24

Then add the two perimeters of both rectangles,

24+30 = 54

Answer:

y=5x+6

Step-by-step explanation:

+6 is six more than.

5x is five times the input.

For example, let's say x=3. you gotta multiply first so you can get the five times out of the way. 3×5=15. Now we got to add six because "6 more than" means to add six. so, 15+6=21. I plugged in 21 for y to check and I got x=3, so this works.

4/6 in fraction form

66% in percentage form

The probability is the ratio of the favorable event to the total number of events. Then the probability of not rolling a 2 is 5/6.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

A fair dice is given.

The total number of the event will be

Total event = 6 {1, 2, 3, 4, 5, 6}

Then the probability of not rolling a 2 on a single die. Then the favorable event will be

Favorable = 1 {1, 3, 4, 5, 6}

Then the probability will be

[tex]P = \dfrac{5}{6}[/tex]

Answer:

x = 19°, <SOR = 17°

Step-by-step explanation:

(5x + 4) + (x - 2) + (3x + 7) = 180°

Combine like terms:

9x + 9 = 180°

9x = 171

x = 19

<SOR = (19 - 2) = 17°

Answer:

(x−3)(x+5) is the factorised form of the expression.

Step-by-step explanation:

x2+2x−15

We can Split the Middle Term of this expression to factorise it.

In this technique, if we have to factorise an expression like ax2+bx+c, we need to think of 2 numbers such that:

N1⋅N2=a⋅c=1⋅(−15)=−15

AND

N1+N2=b=2

After trying out a few numbers we get N1=5 and N2=−3

5⋅(−3)=−15, and 5+(−3)=2

x2+2x−15=x2+5x−3x−15

=x(x+5)−3(x+5)

=(x−3)(x+5) .

(x−3)(x+5) is the factorised form of the expression.

Answer:

(x - 3) and (x + 5) is the factorize form of x² + 2x - 15

Step-by-step explanation:

Julie spent $10 more on the dress.

Step-by-step explanation:

Say the dress's original price is 100.

10% of 100 is 10. so Julie would've paid $90 for the dress

If Mindy buys the same dress when it is 20% off she would've paid $80 for the dress.
