emmainna [20.7K]2 years ago
8 0

Step-by-step explanation:

<em>Perimeter </em><em>of </em><em>a </em><em>rectangle</em><em>=</em><em> </em><em>2</em><em>L</em><em> </em><em>+</em><em> </em><em>2</em><em>W</em>

<em>let </em><em>the </em><em>length </em><em>be </em>2x-1<em> </em><em>and </em><em>breadth</em><em>/</em><em> </em><em>width </em><em>=</em><em> </em>3x+5

52= 2x-1 + 3x+5

52= 5x +4

<em> </em><em>collect </em><em>like </em><em>terms</em><em>;</em>

52-4 = 5x

48=5x

<em>divide </em><em>by </em><em>the </em><em>co- </em><em>efficient </em><em>of </em><em>X</em>

<em>x=</em><em> </em><em>9</em><em>.</em><em>6</em><em>.</em>

<em>hope </em><em>it </em><em>helps.</em><em> </em><em>pls </em><em>like </em><em>and </em><em>follow </em><em>:-)</em><em>:-)</em>

Evaluate the piece wise function for the given values of x by matching the domain values to the range values.
Ugo [173]

Answer:

- 5 (x = 1)

Step-by-step explanation:

When x equals 1, it fits in the piece where x < 3. The equation for that interval is -x - 4. We can substitute 1 into that equation to get:

- 1 - 4

- 5

Help me please find the surface area:
gtnhenbr [62]

Step-by-step explanation:

this consists of 5 sides

top and bottom (equal)

left

right

front

the total surface area is the sum of all 5 areas.

the area of a rectangle is

length × width

the area of a triangle is

baseline × height / 2

in our case we have

top and bottom : 10×4/2 × 2 = 10×4 = 40 cm²

left : 8×9 = 72 cm²

right : 5×9 = 45 cm²

front : 10×9 = 90 cm²

the total surface area is

40 + 72 + 45 + 90 = 247 cm²

Helppp (7th grade) <br><br> _inches
Gekata [30.6K]

Answer:

h = 8 inches

Step-by-step explanation:

Since these shapes are similar and one side of the bigger shape is double the other side (44 is the double of 22), to find side h, you have to multiply 4 by 2 (It's the same relationship between the two sides of similar shapes). 4 times 2 is equal to 8, which is your answer.

What is the values of x if g^x-1 -2=25
Aneli [31]

9^(x - 1) - 2 = 25

9^(x - 1) = 27

ln[9^(x - 1)] = ln 27

ln9(x - 1) = ln 27

xln9 - ln9 = ln 27

xln9 = [ln 27 + ln 9]

x = [ln 27 + ln 9]/ln 9

x = 5/2
