Answer:
gonna solve fore perimeter and area
P = 12 + 3 + 3 + 9 + 9 + 4 + 4 + 4 = 48cm
P = 48 cm
For area or A it is
A = (12*3) + (4*9) = 72 cm^2
Step-by-step explanation:
use deductive reasoning to determine the missing side lengths, and then solve by splitting the figuring into multiple rectangles
Answer:
Step-by-step explanation:
Step 1: Sum of angles on a straight line is 180
Step 2:
2x + 25 + y = 180
2x + y = 180 - 25
2x + y = 155 (1)
Step 3:
3x - 10 + y = 180
3x + y = 180 + 10
3x + y = 190 (2)
Step 4: Substract equation 1 from 2
3x + y - 2x - y = 190 - 155
x = 35
Step 5:
Substitute x in equation 1 to find y
2x + y = 55
2(35) + y = 155
70 + y = 155
y = 155 - 70
y = 85
I dont know if this is right but the answer to 2(12+8x)-3(4x-9) might be 4x+51?
The product of 3p and q-3 would be put in to equation form like this: 3p(q-3)
To find your answer. You have to distribute the 3p to by individually multiplying it by q and -3
It should now look like this:
So your answer is:
