x + y when x = 6 and y = 2

6 + 2 = 8

\frac{9x+24}{4} when x = 12 and y = 20

\frac{148}{4} = 37

\frac{6m}{n} when m = 12 and n = 3

\frac{72}{3} = 24

Six times x

6x

Six increased by x

In a conjunction, / is true when both / and / are _____; otherwise, / is _____.
Crank
So from the onset, the answer to this question would be OPTION B.In a conjunction, / is true when both / and / are<span> TRUE</span>; otherwise, / is FALSE.

A conjunction refers to a compound statement, developed by combining two statement often through the use of the word 'AND'.  For example, the two statements, 'Roses are Red' (statement p) .... 'Violets are Blue' (statement q), can be combined to form a conjunction that reads 'Roses are Red and Violets are Blue.'  When it comes to conjunctions, it is or equivalent to the intersection of the two sets of statements (p and q → p ∩ q) which therefore means that <span>in order for the conjunction to be true, both statements must be true, otherwise, the conjunction is false.
</span>
Attached below is a truth table that seeks to further explain the point (note: ^ represent the conjunction).

What is the length of segment KR?<br><br> A. 3 mm<br> B. 7 mm<br> C. 8.6 mm<br> D. 17.2 mm
marshall27 [118]

Answer:

Option D. KR=17.2\ mm

Step-by-step explanation:

we know that

The Centroid of a Triangle is the center of the triangle that can be calculated as the point of intersection of all the three medians of a triangle. The centroid divides each median in a ratio of 2:1

In this problem the point R represent the centroid of triangle JKL

therefore

KR=(2/3)KM

substitute the value

KR=(2/3)(25.8)=17.2\ mm

Plaz guys help me on this question additional mathematics ​
Soloha48 [4]

Answer:

Step-by-step explanation:

vector OA=a

vector OB=b

vector OX= λ vector OA=λa

vector OY=μ vector OB=μb

a.

1.vector BX=(vector OX-vector OB)=λa-b

ii. vector AY=(vector OY-vector OA)=μb-a

b.

5 vector BP=2 vector BX

5(vector OP-vector OB)=2 (vector OX-vector OB)

5(vector OP-b)=2(λa-b)

5 vector OP-5b=2λa-2b

5 vector OP=2λa-2b+5b

vector OP=1/5(2λa+3b)

ii

complete it.
