Mathematics

Answer:

The line should begin on the right side 2 dashes (the small lines tht go throught the number line. There are 9 dashes between each whole number.)

Then the line should go left because it says x is less than 2/9. (which is right)

The line segment you should choose is the one with the open circle with an arrow going to the left.

A border of uniform width is placed around a rectangular photograph that measures 8 inches by 10 inches. If the area of the bord

amid [387]

Answer:

width of the border is 3 inches

Step-by-step explanation:

Given data

size = 8 inches by 10 inches

area = 144 square inches

to find out

width of the border

solution

first we consider width of border is x

area of new full rectangle = (8 + 2x ) × ( 10 + 2x )

so we know area of photo = 8 × 10 = 80 square inches

and area of border = 144 square inches that is given

so new area of photo with the border is 80 + 144 = 224 square inches

and we can say that

area of full rectangle - area of the photograph = Area of Border

(8 + 2x) × (10 + 2x) – (80) = 144 square inches

80 + 16x + 20x + $4x^{2}$ – 80 = 144

$4x^{2}$ + 36x – 144 = 0

solve thios equation we get

$2x^{2}$ + 9x – 36 = 0

solve thios equation we get

(x + 12) (x – 3) = 0

so here x have two value one is negative and other is positive

so we consider only positive value

x = -12 or x = 3

width of the border is 3 inches

If the area is 27 meters & 6 meters is the height what is the length ?

bezimeni [28]

Area= legnth times width
or sometimes
area=legnth times height
area=measure1 times measure 2 on a flat plane
dependson the names

area=27
height=6
area=legnth times height
subsitute
27=legnth times 6
divide both sides by 6
27/6= legnth
simplified to 4 and 3/4
legnth=4 and 3/4 meter
subsitute

What does c equal in thus equation I don't know for the life of me help is deeply appreciated 4(3+c)+c=c+4

Shkiper50 [21]

Answer:

-2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(3+c)+c=c+4

(4)(3)+(4)(c)+c=c+4(Distribute)

12+4c+c=c+4

(4c+c)+(12)=c+4(Combine Like Terms)

5c+12=c+4

Step 2: Subtract c from both sides.

5c+12−c=c+4−c

4c+12=4

Step 3: Subtract 12 from both sides.

4c+12−12=4−12

4c=−8

Step 4: Divide both sides by 4.

−8

c=−2
