Answer:
1) A
2) I
3) G
4) B
Step-by-step explanation:
1)
Bottom side: 7c - 1
Tall side: 6c + 2
P = 7c - 1 + 6c + 2 + 3c - 2 + 2c + 4c + 1 + 4c + 2
P = 26c + 2
2)
P = 26c + 2
P = 26(5) + 2
P = 132
3)
P = 2(l + w)
P = 2(3d - 2 + 5d + 1)
P = 16d - 2
4)
P = 16d - 2
P = 16(3) - 2
P = 46

P.S. I hope this helps! This may be incorrect, so you may need to check. By the way, remember to try to do at least of the work and not rely too much on Brainly :)
The thing is, these are benchmark fractions and percentages, so they're really important to learn. You use them <em>all the time</em> as you grow older, and you won't always get the chance to look them up. Best of luck ^-^
X + 9y = 5 .....multiply by -1
4x + 9y = -7
-----------------
-x - 9y = -5 (result of multiplying by -1)
4x + 9y = -7
----------------add
3x = -12
x = -12/3
x = -4
x = 5 - 9y
-4 = 5 - 9y
-4 - 5 = - 9y
-9 = - 9y
-9/-9 = y
1 = y
solution is (-4,1)
====================
3x = 5y - 9
-3x = -2y + 3 ....I rearranged this equation from 2y = 3x + 3
----------------add
0 = 3y - 6
6 = 3y
6/3 = y
2 = y
3x = 5y - 9
3x = 5(2) - 9
3x = 10 - 9
3x = 1
x = 1/3
solution is (1/3,2)
====================
10x - 3y = 5....rearranged from 10x - 5 = 3y
2x - 3y = 1...multiply by -1
---------------
10x - 3y = 5
-2x + 3y = -1 (result of multiplying by -1)
---------------add
8x = 4
x = 4/8
x = 1/2
10x - 5 = 3y
10(1/2) - 5 = 3y
5 - 5 = 3y
0 = 3y
0 = y
solution is (1/2,0)
======================
-6x - 4y = 10....multiply by -2
-12x - y = 13
----------------
12x + 8y = -20 (result of multiplying by -2)
-12x - y = 13
-----------------add
7y = - 7
y = -7/7
y = -1
-6x - 4y = 10
-6x - 4(-1) = 10
-6x + 4 = 10
-6x = 10 - 4
-6x = 6
x = -6/6
x = -1
solution is (-1,-1)
1.5 Inches = 3.81 centimeters
So, the plant root would grow 3.81 centimeters per month!
