Answer:

see explanation

Step-by-step explanation:

The first figure is a parallelogram with area (A) calculate as

A = bh ( b is the base and h the perpendicular height )

Here A = 144, b = 16 and h = x, thus

144 = 16x ( divide both sides by 16 )

x = 9

----------------------------------------------------------

The second figure is a trapezium with area (A ) calculated as

A = \frac{1}{2} h (a + b)

where h is the height and a, b the parallel bases

Here A = 480, h = x, a = 37 and b = 27, thus

480 = \frac{1}{2} x (37 + 27) = \frac{1}{2} x × 64 = 32x ( divide both sides by 32 )

x = 15

Simplify with steps.
gogolik [260]

1. (x−1)(5x+8)−2x+5

=(x)(5x)+(x)(8)+(−1)(5x)+(−1)(8)+−2x+5

=5x2+8x+−5x+−8+−2x+5

Combine Like Terms:

=5x2+8x+−5x+−8+−2x+5

=(5x2)+(8x+−5x+−2x)+(−8+5)

=5x2 + x + −3

2. (−2+5)(3x+9)

=9x+27

3. 2x+5−8x+12

=2x+5+−8x+12

Combine Like Terms:

=2x+5+−8x+12

=(2x+−8x)+(5+12)

=−6x+17

4. (−x+3)(−5x−2)

=(−x+3)(−5x+−2)

=(−x)(−5x)+(−x)(−2)+(3)(−5x)+(3)(−2)

=5x2+2x−15x−6

=5x2 − 13x − 6
