Answer:
Constants: 7 and 12
Coefficients: 4
Step-by-step explanation:
A constant is number without a variable next to it, while a coefficient is a number with a variable next to it.
Use Pythagorean theorem
a^2 + b^2 = c^2
C = hypothenuse
8^2 + b^2 = 15^2
64 + b^2 = 225
b^2 = 161
b = square root 161 = 12.68
Solution: 12.7 cm
Answer:
Latoya can plant 5/6 of her garden in one hour.
Step-by-step explanation:
☆We can solve using proportion!
![\frac{ \frac{1}{3 } \: of \: garden }{ \frac{2}{5} \: of \: hour } = \frac{x}{1 \: hour} \\ \\ \frac{ \: \frac { 2}{5}x }{ \frac{2}{5} } = \frac{ \frac{1}{3} }{ \frac{2}{5} } \\ \\ x = \frac{5}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Cfrac%7B1%7D%7B3%20%7D%20%5C%3A%20of%20%5C%3A%20garden%20%7D%7B%20%5Cfrac%7B2%7D%7B5%7D%20%5C%3A%20of%20%5C%3A%20hour%20%7D%20%20%3D%20%20%5Cfrac%7Bx%7D%7B1%20%5C%3A%20hour%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B%20%5C%3A%20%20%20%5Cfrac%20%7B%202%7D%7B5%7Dx%20%7D%7B%20%5Cfrac%7B2%7D%7B5%7D%20%7D%20%20%3D%20%20%5Cfrac%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%7B%20%5Cfrac%7B2%7D%7B5%7D%20%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B5%7D%7B6%7D%20)
Each side of the square would be 80/4 = 20 cm. so its area = 20^2 = 400 cm^2.
Th rectangle will have perimeter = 80 = 2x + 2(x - 12) where x = height of the rectangle
4x = 80+24 = 104
so x = 26
area of rectangle = 26*(26-12) = 364 cm^2
