Step-by-step explanation:

If a+b=50

When b=30

a=50-b

a= 50 - 30

a=20

Therefore 20(a)+30(b)=50

The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.
seropon [69]

Answer: Option B.

Step-by-step explanation:

Given the polynomial:

16x^2-36x+9

 Observe that 16x^2 and 9 are perfect squares. Then, you can rewrite the polynomial in this form:

(4x)^2-36x+(3)^2

You can identify that:

A=4\\B=3

Then, we can check if 2AB=36

 2(4x)(3)=36x\\\\24x\neq 36x\\\\2AB\neq36x

Since 2AB\neq36x, the polynomial 16x^2-36x+9 <em>IS NOT </em>a perfect square trinomial of the form A^2 - 2AB + B^2

Answer the questions below about Line 1 and Line 2 shown below.
givi [52]
  1. The expression was rewritten using the commutative law of addition.
  2. Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots.
  3. Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.

<h3>What is the commutative law of addition?</h3>

The commutative law of addition is also referred to as the law of cumulative addition and it states that if two numbers are added together, then, the outcome is equal to the addition of their interchanged position because addition is considered as a binary operation.

This ultimately implies that, the sum of addends would always be the same (equal) regardless of their arrangement in accordance with the commutative law of addition. Mathematically, the commutative law of addition can be represented using the following formula:

A + B = B + A.

In this context, we can reasonably infer and logically deduce that the given expression was rewritten using the commutative law of addition.

In conclusion, Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots. Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.

Explain what you can tell just by comparing the symbols in the picture graph
olchik [2.2K]
Picture graphs usually show amounts using...pictures! So if you looked at the symbols, you can likely guess the amounts. It might show how many students preferred hamburgers by using a hamburger to represent every 5 students. Just by quickly glancing at a picture graph, you can usually tell which result is the greatest.

I need help with this question, I can work out the ratio but I am just confused with the question. So do help if you can please.
nirvana33 [79]

Answer:

76%

Step-by-step explanation:

So basically 528 represents a full circle and the amount in the circle is 2:5 to that in the stalls.

So you divide 528 by 2 and then multiply it by 5 to get a full stall of 1320

you then add 1320 and 528 to get a full theater of 1848

to get 2/3 of seats in the stall you divide 1320 by 3 and then multiply it by 2 to get 880.

For 2/3 of the stall and a full circle you add 880 and 528 to get 1408.

You divide the amount of people in the theater on Friday by the total amount of people which the theater can hold so 1408 divided by 1848 and you get the percentage of 76%
