Aliun [14]

Answer: 2

Step-by-step explanation: That expression is a binomial in any case the terms in a polynomial are separated by a plus or minus sign (+,-) so you can determine the number of terms by counting how many number or variable are being separated (ex: 3a+a-1 would have 3 terms and be a trinomial)

DanielleElmas [232]

Answer:

The price of a single printer cartridge is 19.69, in your given currency.

Step-by-step explanation:

First remove the tax and the software package from the total bill.

90.01 - 24.99 - 5.95 = 59.07

Since there are 3 cartridges, you divide 59.07 by 3, giving you the price of a single cartridge.

59.07 \div 3 = 19.69

Can someone please help me find the measure of angle ABO?
lara [203]

Answer:

m<ABO = 22 deg

Step-by-step explanation:

A tangent intersects a circle at the point of tangency making a right angle with the radius drawn to that point. That means that <BAO is a right angle and measures 90 deg. That makes the other two angles of the triangle complementary with a sum of 90 deg.

m<O + m<B = 90

68 + m<B = 90

m<B = 22

Answer: m<ABO = 22 deg

Gloria decides to buy 4 ferns, 2 Palms, 10 Lilies and 8 shrubs. To show the total
Vadim26 [7]

Answer:

Total Plants = 4F + 2P + 10L+ 8S

Total Plants = 2(2F + P + 5L+ 4S) --- Distributive property

Step-by-step explanation:

Given

Ferns = 4

Palms = 2

Lillies = 10

Shrubs = 8

Required

Show the total cost of plants as an expression

Shorten it using the distributive property

First, represent Ferns with F; Palms with P; Lilies with L and Shrubs with S;

So, 4 Ferns = 4F

2 Palms = 2P

10 Lilies = 10L

8 Shrubs = 8S

Total Plants = Summation of the above parameters

Total Plants = 4F + 2P + 10L+ 8S

The above expression represents the total plants bought;

Now, to apply the distributive property; we simply look for a common factor;

In this case, the common factor is 2;

So, Total Plants = 4F + 2P + 10L+ 8S becomes

Total Plants = 2(\frac{4F}{2} + \frac{2P}{2} + \frac{10L}{2}+ \frac{8S}{2})

Total Plants = 2(2F + P + 5L+ 4S)
