7 0

Answer:

  114 square meters

Step-by-step explanation:

The figure decomposes into two congruent trapezoids, each with bases 15 m and 4 m, and height 6 m. The area formula for a trapezoid is ...

  A = 1/2(b1 +b2)h

__

Each trapezoid will have an area of ...

  A = 1/2(15 +4)(6) = 57 . . . . square meters

The figure's area is twice that, so is ...

  figure area = 2 × 57 m² = 114 m²

What is the perimeter of a rectangle with a length of (x^2+x) and a width of (2x^2+3x)
Mazyrski [523]

Answer:

Perimeter = 6x² + 8x

Step-by-step explanation:

Perimeter = 2(length + width)

perimeter = 2((x²+x)+(2x²+3x))

perimeter = 2(x²+2x² + x+3x)

perimeter = 2(3x² + 4x)

perimeter = 2*3x² + 2*4x

perimeter = 6x² + 8x

Can you help meee get this ?

Answer: y=4/5x-2 or y=4/5x+(-2)

Step-by-step explanation:

The formula for slope-intercept form is y=mx+b.

To find the slope, we can use the formula m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  } and plugging in the points given.

m=\frac{6-2}{10-5} =\frac{4}{5}

We know our slope is 4/5. We can plug this into our slope-intercept form and then plug in a point to find b, y-intercept.

y=\frac{4}{5} x+b

2=\frac{4}{5}(5)+b

2=4+b

b=-2

We know the y-intercept is -2.

THe final equation is y=4/5x-2 or y=4/5x+(-2).
