Step-by-step explanation:
a=4 so 3a becomes 3x4.
3x4=12
12+6c^2
C=2 so 6c^2 becomes (6x2)^2
6x2=12 and 12x12 because of the exponent.
12x12=144
12+144=156
If it's wrong, i'm sorry
Answer:
a = 5
b = -4
c = -20
Step-by-step explanation:
Here, we want to express the given equation in the following form;
So we can have this as;
5x-4y-20 = 0
That means we have;
a as 5
b as -4
and c as -20
<span>3^3 ÷ 9 / 11 - 2^2
=27 </span>÷ 9 / 11 - 4
= 27 * 11/9 -4
= 297/9 - 4
=33-4
=29
the length of the shorter side is:L = 13.125cm
<h3>
how long will the shorter side be?</h3>
In the longer side we have 8 segments.
We know that the side measures 35 cm, then each one of the 8 segments measures:
35cm/8 = 4.375cm
Now, we can see that in the shorter side we have 3 of these segments.
Then the length of the shorter side is:
L = 3*(4.375cm) = 13.125cm
