Answer:
2z+6
Step-by-step explanation:
you just multiply the z and 3 by 2.
Answer:
6 Dallas
Step-by-step explanation:
30 percent of 20$ is 6$
30 percent *20 =
( 30:100)*20 =
( 30*20):100 =
600:100 = 6
Answer:
Step-by-step explanation:
in tri ADC and tri BDC
∠ADC =∠BDC = 90
DC is common
AD = BD (given)
triangle ADC ≅ tri BDC by SAS congruency
hence AC = BC by CPCT ( congruent parts of congruent triangles)
hence, BC = 13
The inequality that describes the possible values of the expression is:

<h3>What is the lower bound of values of the expression?</h3>
The expression is given by:

To find the lower bound, we try to see when the expression is negative, hence:


Applying cross multiplication and simplifying the 3's, we have that:

From the bounds given, this expression will never be true, at most they can be equal, when:
a = b = 4.
Hence the lower bound of values of the expression is of 0.
<h3>What is the upper bound of values of the expression?</h3>
The expression is a subtraction, hence we want to maximize the first term and minimize the second.
Considering that the first term is direct proportional to b and inverse to a, and the second vice versa, we want to:
Then:

Hence the bounds are:

Answer:
see explanation
Step-by-step explanation:
(1)
p + q
= 2i - j + i + j ← collect like terms
= 3i
(2)
p - q
= 2i - j - (i + j) ← distribute parenthesis by - 1
= 2i - j - i - j ← collect like terms
= i - 2j
(3)
2p - 3q
= 2(2i - j) - 3(i + j) ← distribute parenthesis
= 4i - 2j - 3i - 3j ← collect like terms
= i - 5j
