Answer:
B
Step-by-step explanation:
The first term of the binomial needs to be multiplied by the entire trinomial. We'll use the distributive property to expand. Now we do the same process for the second term. The last step is to combine the two parts and simplify.
Answer:
A = 30
Step-by-step explanation:
x = 5
y = 10
A = xy - 20
substitute 5 and 10 in the place of x and y
(5*10) - 20
50 - 20
30
A = 30
Answer:
That is a 30 60 90 triangle.
In such a triangle the "middle" size = short side * sq root (3)
height = 5 * sq root (3) = 8.6602540378
Area = (1/2) * 5 * 8.6602540378
Area = 2.5 * 8.6602540378
Area = 21.6506350946 square centimeters
Step-by-step explanation:
Every triangle has an angle measure of 180 degrees.
so 42+20+x (where x is the measure of the third angle)=180
Combine like terms.
62+x=180
Subtract 62 from both sides
x=118.
Answer:
The price for a small glass of milk is $0.95, and the price for a breakfast taco is $1.15.
Step-by-step explanation:
Let the price of a taco be x and the price for a small glass of milk be y.


Multiply the first equation by 2:

Subtract the new third equation from the second equation:


Hence, the price for a small glass of milk is $0.95.
Substitute y into the first equation.


Therefore, the price for a breakfast taco is $1.15.
Hope this helped!
