Just remember the syllables PEMDAS which stand for Parentheses, Exponents, Multiplication, Division, Addition and Subtraction. If you can’t remember it, just write it on the side of your paper. But make sure to use it in that order.

Answer:

1)   5x³ + 3x²

2)  25 - 3x⁵

3)  -4ab + 2a² + 26

4)   p²q³ + pq

Step-by-step explanation:

Like terms are expressions like 3x and 2x or 5x² and 8x².

1)  x² + 5x³ + 2x²

    5x³ + 3x²

2)  -2x⁴ + 16 + 2x⁴ + 9 - 3x⁵

     -2x⁴ + 2x⁴ + 25 - 3x⁵

      25 - 3x⁵

3)  ab - a² + 4² - 5ab + 3a² + 10

     ab - a² + 16 - 5ab + 3a² + 10

     ab - a² - 5ab + 3a² + 26

     ab - 5ab + 2a² + 26

     -4ab + 2a² + 26

4)  3p²q² - 3p²q³ + 4p²q³ - 3p²q² + pq

     3p²q² + p²q³ - 3p²q² + pq

     p²q³ + pq

There are 7/8 kilograms of salt in the kitchen. Mrs. Jackson used 2/15 of salt when preparing dinner . How much salt did she use
neonofarm [45]

so since Mrs Jackson used 2/15 of 7/8, the amount she used is simply their product.


\bf \stackrel{\textit{how much is }\frac{2}{15}\textit{ of }\frac{7}{8}?}{\cfrac{7}{8}\cdot \cfrac{2}{15}}\implies \cfrac{7}{15}\cdot \cfrac{2}{8}\implies \cfrac{7}{15}\cdot \cfrac{1}{4}\implies \cfrac{7}{60}

Find the slope of this graph, thanks
Anarel [89]

Slope  =  (change in 'y') / (change in 'x')

If you find two points where the line goes through the corners of boxes,
then count up the 'y' boxes and the 'x' boxes between those two points,
you'll find that the line rises 3 y-boxes for each x-box.

The slope of the line is  3 .

A triangle has sides of LaTeX: 1\frac{1}{6}1 1 6 inches, LaTeX: 1\frac{1}{3}1 1 3 inches, and LaTeX: 1\frac{2}{3}1 2 3 inches. W
Nuetrik [128]

Answer:

4 1/6 inches

Step-by-step explanation:

A triangle has sides of LaTeX: 1\frac{1}{6}1 1 6 inches, LaTeX: 1\frac{1}{3}1 1 3 inches, and LaTeX: 1\frac{2}{3}1 2 3 inches. What is the perimeter of the triangle? Make sure your answer is in simplest form.

Perimeter of Triangle = Side a + Side b + Side c

Perimeter of the Triangle =

( 1 1/6 + 1 1/3 + 1 2/3) inches

Lowest common denominator = 6

= 1 + 1 + 1 +(1/6 + 1/3 + 2/3)

= 3 + (1 + 2 + 4/6)

= 3 + 7/6

= 3 + 1 1/6

= 4 1/6 inches
