In the figure, the dashed line divides the arrow in half. What is the total area of the arrow? 60 square centimeters 68 square c

WARRIOR [948]

Answer:

80 square centimeters

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The total area of the arrow is equal to the area of a rectangle plus the area of a triangle

step 1

Find out the area of the rectangle

The area of rectangle is equal to

$A_1=LW$

we have

$L=17\ cm\\W=4\ cm$

substitute

$A_1=(17)(4)=68\ cm^2$

step 2

Find the area of triangle

The area of triangle is equal to

$A_2=\frac{1}{2}(b)(h)$

we have

$b=4+2+2=8\ cm\\W=20-17=3\ cm$

substitute

$A_2=\frac{1}{2}(8)(3)=12\ cm^2$

step 3

The area of the arrow is equal to

$A=A_1+A_2$

substitute the values

$A=68+12=80\ cm^2$

I would say the answer is the first option. Usually when it asks for opposites, it wants something like the opposite of 15 is -15. Putting a negative on the outside means you solve the same, but you just add a negative sign on the number,

What's 4 (-x + 1 ) = -2 (x + 2) ?

alexira [117]

Answer:

x = 4

Step-by-step explanation:

Simplify then isolate x

4 (-x + 1 ) = -2 (x + 2) Distribute across brackets

-4x + 4 = -2x - 4 Add 2x to both sides

-2x + 4 = -4 Subtract 4 from both sides

-2x = -8 Divide both sides by -2

x = 4
