4y=12-2x
y=(12-2x)/4
-------------
Start by breaking the figure into simpler figures
Triangle 1
Triangle 2
Square
Then calculate the area for each one
Square: 2 cm times 2 cm = 4 cm
Triangle: 2 cm times 1 cm = 2 cm divided by 2 = 0.5 cm
Triangle: 2 cm times 1 cm = 2 cm divided by 2 = 0.5 cm
Add up all the values and get 5 cm squared
Answer: m=13
Step-by-step explanation:
Basically you solve this by finding out what plus 4 equals 17. You can do this by subtracting 4 from 17.
17-4=13
This is how you find the value of m.
Answer:
96 oz.
Step-by-step explanation:
Mary drinks 24 ounces a day Lena drinks 3 times a much
24 x 3 = 72
72 + 24 = 96
Answer:
20
Step-by-step explanation
use the formula a²+b²=c²
since a=21 and c=29 you need to solve for b
Put 21 in for a and 29 in for c
21²+b²=29²
21²=441
29²=841
so then the equation would be 441+b²=841
subtract both sides by 441
then you have b²=400
now just find the square root of 400
√b²=√400
b=20
