The stage of the commander's decision cycle is facilitated by the commander's intent; ccirs also assist the jtf hq in this role.
a. direct
b. monitor
c. assess
d. plan

a. direct

Explanation:

According to the Commander's critical information requirements (CCIR) presents guidelines or methodologies for the Joint Task Force Headquarters (JTF HQ) during military drills and other scenarios. In this regard, the stage in which the commander's decision cycle is facilitated by the commander's intent is the direct stage in which the support is provided to the commander's decision. This is covered in objective 175 of the CCIR.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7
