I'm going to assume the 4 and 3 are exponents and the expression is .
The first step is to separate the coefficients of 3 and -6 from the variables and to multiply those as normal:
As for the variables, you want to recognize that means and means , so
In total, there are 7 a's being multiplied, so
Putting this all together, we have:
Answer:
7/4
Step-by-step explanation:
The statement " the measure of angle ABD is 50 degrees, and it is
given that angles ABD and DBC are complementary " justifies why
∠DBC measures 40° ⇒ last answer
Step-by-step explanation:
Let us revise some fact s about angles
1. If two angles are supplementary then the sum of their
measures is 180°
2. If two angles are complementary then the sum of their
measures is 90°
∵ ∠ABD and ∠DBC are complementary ⇒ given
∴ m∠ABD + m∠DBC = 90°
∵ m∠ABD = 50°
∴ 50 + m∠DBC = 90°
- Subtract 50 from both sides
∴ m∠DBC = 40°
The statement " the measure of angle ABD is 50 degrees, and it is
given that angles ABD and DBC are complementary " justifies why
∠DBC measures 40°

Answer:
14.7 inches
Step-by-step explanation:
To solve this we use Pythagorean Theorem, so a**2 + b**2 = c**2
Since we have The hypotenus (19”) and the opposite (12”), we rearrange it to be , b equals the square root of c squared - a squared.
When we plug the numbers in the formula, the answer is 14.73, which is therefore 14.7 inches!
Hope this helps!
Answer:
3
Step-by-step explanation:
1/3 of 9 is 3
you would figure this out by dividing the total amount of books by the denominator of the fraction.
9/3=3
