Your answer is 0.03 because you have to make the 5 equal to the ten and that would be 10 then change the division to multiplication and just multiply across then you simplify it.
Equilateral triangle have the same side lengths. Perimeter = sum of all sides
(4x - 3) + (4x - 3) + (4x - 3) = 63
Remove parentheses
4x - 3 + 4x - 3 + 4x - 3 = 63
Combine like terms
12x - 9 = 63
12x = 72, x = 6
Solution: x = 6
Answer:
<u>193.2 cm²</u>
Step-by-step explanation:
Area = 5.2 x 6 + 3 x 6 x 9
= 31.2 + 162
= <u>193.2 cm²</u>
Answer:
704
Step-by-step explanation:
7000 + 40 (7 thousands + 4 Tens) Divide that by 10.
7040/10 = 704
x=3
multiply 2 to both sides to cancel denominator
subtract 8x from both sides and then divide by 2
