<h2>Explanation:</h2><h2></h2>

Combining like terms is used in math in order to simplify expressions. We combine common terms in order to make the expression much easier. Common terms are those that have the same variable and exponent. So in the expression:

3.26d+9.75d-2.65 \\ \\ \\ So: \\ \\ \text{The terms} \ 3.26d, \ 9.75d \ \text{have the same variable d and exponent 1} \\ \text{therefore we can combine them}

Thus, the expression becomes:

3.26d+9.75d-2.65=(3.26d+9.75d)-2.65=\boxed{13.01d-2.65}

Here is your great answer Simplifying
4x2y + 12xy2 + 9y3

Reorder the terms:
12xy2 + 4x2y + 9y3

Factor out the Greatest Common Factor (GCF), 'y'.
y(12xy + 4x2 + 9y2)

Factor a trinomial.
y((2x + 3y)(2x + 3y))

Final result:
y(2x + 3y)(2x + 3y)

M∠1=(3x+8)°​, m∠2=(3x+18)°​, and m∠3=(7x+9)°. What is m∠​3?
deff fn [24]

Answer:

87.4°

Step-by-step explanation:

(3x + 8) + (3x + 18) + (7x + 9) = 180

3x + 8 + 3x + 18 + 7x + 9 = 180

add the common numbers

13x + 35 = 180

subtract 35

13x = 145

divide 13

x = 11.2

then plug it back in to m<3

7(11.2) + 9

78.4 + 9

= 87.4°

Liz purchased three trays of tomato plants for $16.47. She also bought ten trays of basil plants. If the ratio of the price per
Yuki888 [10]

Answer:

53.07$

Step-by-step explanation:

I calculated 2/3 of 16.47 and got 10.98. I divided 10.98 by 3 to get 3.66.

3.66$ is the cost of 1 tray of basil plants.

Then I multiplied 3.66 by 10 and got 36.60

I added that to the cost of tomatoes and got my answer

I hope I did it right, good luck with your assignment <3

What is the value of the expression below when x=3<br> 10x²- 7x + 10
Andreas93 [3]

Answer: 79

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

<u>Given information</u>

10x² - 7x + 10

x = 3

<u>Substitute the value into the expression</u>

= 10 (3)² - 7 (3) + 10

<u>Simplify by multiplication</u>

= 10 (9) - 21 + 10

= 90 - 21 + 10

<u>Simplify by subtraction</u>

= 69 + 10

<u>Simplify by addition</u>

= 79

Hope this helps!! :)
