Answer:
21. 3x^2 +7x
22. 6x^3 +3x
Step-by-step explanation:
21. The perimeter is the sum of the side lengths.
P = (x^2 +3x +1) +(4x -1) +(2x^2)
P = x^2(1 +2) +x(3 +4) +(1 -1) . . . . combine like terms
P = 3x^2 +7x
__
22. The area is the product of the dimensions.
A = (3x)(2x^2 +1)
A = 6x^3 +3x . . . . . use the distributive property
Answer:
3/6=7/2/7 the blank is 7/2
T= total length
T=1 2/5 meters + 4 1/5 meters
add the whole #s and the fractions
T= (1+4) + (2/5 + 1/5)
T= 5 3/5 meters total
Hope this helps! :)
Answer:
Colinear is lying in the same straight line or linear sequence.
Step-by-step explanation:
So, if you find those, that is the answer. Please mark as brainliest! =) Hope this helps =). If you mark me as brainliest I will level up! Much appreciated!
-2(y = x - 2) -----> -2y = -2x + 4
y = 2x + 4 --------> + y = 2x + 4
-1y = 8
/ -1 /-1
y = -8
y = x -2
-8 = x -2
+ 2 +2
-6 = x
The answer is ( -6, -8)
