Area is length times width [A=(L)(W)], if we know that the area of the card is 3/10 and the length is 4/5 we can set up the equation 3/10=(4/5)(W) where W is width. Solve for W by deciding both sides by 4/5 and we get that W=3/8. To find the perimeter of the card were have to add up all the sides of the card so 3/8+3/8+4/5+4/5 which equals 47/20
Answer:
-28 + 7x
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define</u>
-7(4 - x)
<u>Step 2: Simplify</u>
- Distribute -7: -7(4) - 7(-x)
- Multiply: -28 + 7x
B1 = 0.125
b2 = - 0,25
q = b2/b1 = - 0,25/0,125 = - 2
b5 = b1*q^4 = 0,125*(-2)^4 = 0,125*16 = 2
A
It should be b but i don’t have paper with me so i’m not sure
Answer:
5
Step-by-step explanation:
