I hope this helps you
x= 3
f (3)= 3.3^2-2= 27-2=25
g (3)= 3+7=10
f (3)-g (3)= 25-10= 15
Answer:
5.82
Step-by-step explanation:
582 / 100 = 5.82
you divide the number by 100 to get your decimal.
Answer:
270°
Step-by-step explanation:
(0, -1) is at the 270° angle. If you do a 360°, you end up back where you started, so the angle is still 270°.
Answer:
No, that is not a solution
Step-by-step explanation:
Plug in the numbers to their respective values, so -1 to x, and 5 to y.
2(-1) + 5(5) = 0
-2 + 25 = 0
23 = 0?
No, that is not a solution
Answer:
Option C 24 in
Step-by-step explanation:
Let
x-----> the length of each rod
b -----> the length side of the square
a -----> the length side of the equilateral triangle
we know that
The perimeter of the square is 4b
The perimeter of equilateral triangle is 3a
so
2x=4b+3a ------> equation A
4b=3a -----> equation B
a=b+2 ----> equation C
<em>Substitute equation C in equation B and solve for b</em>
4b=3(b+2)
4b=3b+6
4b-3b=6
b=6 in
<em>Find the value of a</em>
a=b+2 ------> a=6+2=8 in
Find the value of x
x=4b or x=3a
x=4(6)=24 in
therefore
The length of each rod is 24 inches
