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

Arrange the expressions below in order from least to greatest. Place the least at the top and greatest at the bottom.

Answers

Step-by-step explanation:

(72/8) - 2 * 3 + 1

= 9 − (2) (3) + 1

= 9 − 6 + 1

= 3 + 1

= 4

72/(8 - 2) * 3 + 1

= 72/6(3) + 1

= (12)(3) + 1

= 36 + 1

= 37

72/(8 - 2) * (3 + 1)

= 72/6(3 + 1)

= 12(3 + 1)

= (12)(4)

= 48

72/8 -2 * (3+1)

= 9 - 2(3 + 1)

= 9 - (2)(4)

= 9 - 8

= 1

All that is left for you to do is to order them. Good luck! :)

The measure of ∠4 is 34°. What are the measures of ∠1, ∠2, and ∠3, respectively?

A. ∠1 = 146°, ∠2 = 146°, ∠3 = 34°
B. ∠1 = 146°, ∠2 = 34°, ∠3 = 146°
C. ∠1 = 124°, ∠2 = 34°, ∠3 = 124°
D. ∠1 = 34° , ∠2 = 146°, ∠3 = 34°

DONT PUT NONSENSE ANSWERS

Answers

Answer:

B

Step-by-step explanation:

∠4 and ∠2 are vertical angles

Vertical angles are congruent

Which means that because ∠4 = 34°, ∠2 also = 34°

∠1 and ∠4 are supplementary angles.

Supplementary angles add up to equal 180

Which means that ∠1 + ∠4 = 180

or ∠1 + 34° = 180

subtract 34 from each side

180 - 34 = 146

Hence, ∠1 = 146

∠1 and ∠3 are vertical angles

Like stated before vertical angles are congruent

Which means that because ∠1 = 146°, ∠3 also = 146

So we can conclude that the answer is B

Answer:

B) <1 = 146, <2 = 34, <3 = 146

Step-by-step explanation:

Because measure angle 4 is 34°

And the angle opposite of <4 is <2 and they’re both congruent so <4 = <2. Therefore, <2 = 34.

By finding <1 and <3 is simply finding a supplementary angle because:

<4 + <1 = 180°

<4 + <3 = 180°

So,

34 + <1 = 180°

<1 = 146°

and,

34 + <3 = 180°

<3 = 146

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:

[tex] {x}^{2} + 2x - 15[/tex]
