What is the area of this trapezoid?

Oksi-84 [34.3K]

Answer:

The answer is option b 130cm²

Area of a trapezium is 1/2(a + b) × h

where 'a' and 'b' are the parallel sides of the trapezium

h is the height

From the picture above

h is 10cm

'a' and 'b' are 17cm and 9 cm respectively

Area of the trapezium = 1/2 ( 17+9)× 10

= 1/2× 26 × 10

= 13 × 10

= 130cm²

What statement about -2h^2 - 15h - 7 is true?

stepan [7]

Answer : one of the factor is (2h+1)

$-2h^2 - 15h - 7$

LEts factor the given expression

WE have negative in common

so we factor out negative

$-(2h^2 + 15h + 7)$

Now we multiply 2 and 7 = 14

We find out two factors whose product is 14 and sum is 15

1 times 14 = 14

1 + 14 = 15

So two factors are 1 and 14

Now split the middle term 15h using factors 1 and 14

$-(2h^2 + 1h + 14h + 7)$

We group first two terms and last two terms and factor out GCF

$-(2h^2 + 1h) + (14h + 7)$

$-h(2h+ 1) + 7(2h + 1)$

$- (2h+ 1)(h+7)$

So one of the factor is (2h+1)
