Can someone please help me?<br> If g(x) = x2 - 5x + 2, find g(0).

Debora [2.8K]

g(x) = x² - 5x + 2

You are looking for g(0). This means that you must replace all the x values in the equation above with 0

(0)² - 5(0) + 2

Now you need to solve according to the rules of PEMDAS:

(0)² - 5(0) + 2

0 - 5(0) + 2

0 - 0 + 2

0 + 2

g(0) = 2

Hope this helped!

Each small square on this scale weighs 1 unit. Each larger square weighs 10 units. The weight of the triangle x is unknown. The

Iteru [2.4K]

The equation to represent the relationship of the weights shown on the scale s $22 + x = 34$

The weights are given as:

$Small\ Square = 1$

$Larger\ Square = 10$

The total weight on one side, where there are 4 small squares and 3 large squares is:

$Total =4\times Small\ Square + 3 \times Larger\ Square$

$Total =4\times 1 + 3 \times 10$

$Total =34$

The total weight on the other side, where there are 2 small squares, 2 large squares and 1 triangle is:

$Total =2\times Small\ Square + 2 \times Larger\ Square + 1\times triangle$

$Total =2\times 1+ 2 \times 10+ 1\times triangle$

$Total =2+ 20+ 1\times triangle$

$Total =22+ 1\times triangle$

$Total =22+ triangle$

The weight of the triangle is x.

So, we have:

$Total =22+ x$

The weights on both sides are equal, because the scale is balanced.

So, we have:

$22 + x = 34$

Hence, the equation is $22 + x = 34$
