Answer:
7/6
Step-by-step explanation:
The width to length ratio is ...
... width / length = (4 2/3 yards)/(4 yards) = (14/3)/4 = 14/12
... width/length = 7/6
The answer is 2(2x-3)
Explanation: First you multiple 5 and 2 getting you ten
4x-10+4
Then you add -10 and 4 to get -6
4x-6
Finally you factor out the number to and divide both the 4 and -6
2(2x-3)
Answer:
9x
9 • x
9(x)
9*x
I think that's what the question means?
Answer:
C
Step-by-step explanation:
the area of a triangle is
baseline × height / 2
so, we know in our case
b(b+12) = 189 cm²
b² + 12b - 189 = 0
let's try to solve this by completing the square.
that means we try to find the expression
(b + k)² + c
that is equal to
b² + 12b - 189
(b + k)² + c = b² + 2kb + k² + c = b² + 12b - 189
so,
2k = 12
k = 6
and then
k² + c = -189
6² + c = -189
36 + c = -189
c = -225
(b + 6)² - 225 = 0
(b + 6)² = 225
b + 6 = 15
b = 9
so, the baseline b = 9 cm.
the height b+12 = 9+12 = 21 cm.
Here are the steps to solve the equation. Good luck!
