Answer:
(x-4) (x-5)
Step-by-step explanation:
x^2 -9x+20
What two number multiply to 20 and add to -9
-4*-5 = 20
-4+-5 = -9
(x-4) (x-5)
2.19 2.19 9.855 + 7.1175 = (approximately) <u>$16.97</u>
x 4.5 x 3.25
----------- ----------
9. 855 7.1175
I hope this helps!!
The answer is letter a. m∠BAD = 108.42<span>°
The solution is as follows:
If </span>m∠BAC = 40.62° and m∠BCA = 30.96°, then
m∠CBA = 180° - m∠BCA - <span>m∠BAC
</span>m∠CBA = <span>108.42°
</span>
Since m∠BAD = m∠CBA due to the parallelogram's property,
<span>m∠BAD</span> = <span>108.42°.</span>
Answer:
Weight of dog: 34 pounds,
Weight of cat: 12 pounds.
Step-by-step explanation:
Let d represent weight of dog and c represent weight of cat.
We have been given that a dog weighs two pounds less than three times the weight of a cat.
3 times weight of cat: 
We can represent the given information in an equation as:

We are also told that the dog also weights twenty-two more pounds than the cat. We can represent the given information in an equation as:

Equate both equations:






Therefore, the weight of cat is 12 pounds.
Substitute
in equation (2)



Therefore, the weight of dog is 34 pounds.
