Answer:
a
20cm squared
b
18cm
c
5cm
d
80cm
Step-by-step explanation:
a
Area is height multiplied by length in a regular quadrilateral
b
Perimeter is calculated by adding all the sides together
c
0.5 is effectively halving, so instead of 4 multiplied by 5 it is 2 multiplied by 2.5
d
2 is effectively doubling, so instead of 4 multiplied by 5 it is 8 multiplied by 10
Ok so if the parenth function is y=x^2
to move it up c units, add c to whole function
to move it right c units, minus c from every x
looks like we have
y=(x-6)^2-5
add -5 to whole funciton
minus 6 from every x
means that it moved 5 units down and 6 to the right from original function if parenth is y=x^2
Answer:
81
Step-by-step explanation:
x² + 18x
x² + 2(x)(9) + 9²
x² + 2(x)(9) + 81
(x + 9)²
Answer:
<u><em>Mabye just explain it to us</em></u>
I'm pretty sure it's D = 3t + 8
I hope this helps!
