Answer:
-8k - 15
Step-by-step explanation:
5(-2k-3)+2k
At first, we will break the parenthesis. To break that, we will multiply the value inside the parenthesis by the adjacent number, that is 5. Again, we have to consider the Algebraic operation (Golden rule) -
[(-) x (-) = (+); (+) x (-) = (-)]
Therefore, since there is a minus sign in each of the value inside the parenthesis, the result will be minus as 5 is a positive integer.
or, -5*(2k) - (5*3) + 2k
or, -10k - 15 + 2k
or, -8k - 15 (after the deduction)
The answer is = -8k - 15
Answer:
Using trigonometric ratio:
From the given statement:
and sin < 0
⇒
lies in the 3rd quadrant.
then;
Using trigonometry identities:
Substitute the given values we have;
Since, sin < 0
⇒
now, find 
:
Substitute the given values we have;
Therefore, the exact value of:
(a)
(b)
Answer:
y=29
Step-by-step explanation:
Replace x with 7:
y=8+3(7)
Multiply 7 and 3:
y=8+21
Add together:
y=29
Answer:
80
Step-by-step explanation:
we search for a square number so that rows*plantsInARow gives us the number
The number should be around 50², guessed
50² = 2500 (to low)
51² = 2601 (still to low)
52² = 2704 (bingo)
now to get from 2624 to 2704 plants he needs 80 more. That is the least number.
He could also go to plant 60² plants an than need slot more.

Answer:
see below
Step-by-step explanation:
h(x) = 2x-10
Let x=3
h(3) = 2*3 -10
= 6-10
=4
Let x=-3
h(-3) = 2*-3 -10
= -6-10
=-16
