Answer:

f(-3) = 44

Step-by-step explanation:

f(x) = 2x² - 5x + 11

Substitute the value.

f(-3) = 2(-3)² - 5(-3) + 11

Raise -3 to the power of 2.

f(-3) = 2(9) - 5(-3) + 11

Multiply 2 and 9.

f(-3) = 18 - 5(-3) + 11

Multiply -5 and -3.

f(-3) = 18 + 15 + 11

Add 18 and 15.

f(-3) = 33 + 11

Add 33 and 11.

f(-3) = 44

Parallelogram H G J L is shown. Diagonals are drawn from point H to point J and from point G to point L and intersect and point

Ghella [55]

Answer:

50 units.

Step-by-step explanation:

It is given that HGJL is a parallelogram and diagonals intersect each other at point K.

$HK=c-7,JK=3c-33,GK=c+12$

We now that diagonals of parallelogram bisect each other. So,

$HK=JK$

$c-7=3c-33$

$33-7=3c-c$

$26=2c$

Divide both sides by 2.

$13=c$

Now,

$GK=c+12=13+12=25$

Diagonals of parallelogram bisect each other. So,

$GL=2(GK)=2(25)=50$

Therefore, the measure of GL is 50 units.
