Answer:

Step-by-step explanation:

Expression given:

1/2(3a + 4b + c) – (c2 + 5a)

Given:

a = 3

b = 25

c = 5

Solve:

We can substitute each to find the answer:

1/2(3a + 4b + c) – (c2 + 5a)

1/2(3(3) + 4(25) + (5) ) - ((5)2+5(3)

1/2 (114) - (25)

57 - 25

Answer:

100

Step-by-step explanation:

$4\times(2+3)^{2}$

This can be turned into:

$4\times5^{2}$ (if we add the numbers inside the brackets)

Following PEDMAS, this becomes:

$4\times25$ which equals $100$

∴ $4\times(2+3)^{2}=100$

You can look for these:

Step-by-step explanation:

The factors of the equation:

For example, if multiplication, the factors 2x2=4

if addition, the addends 2 + 2= 4

So just look for the numbers before the equal sign and any key words in the problem.

Hope this helps!

Consider the function f(x)=-2x+5 what is f(5) enter your answer in the box

Oliga [24]

The value of f(5) is $f(5)=-5$

Step-by-step explanation:

The function is $f(x)=-2x+5$

To find $f(5)$ substitute $x=5$ in $f(x)=-2x+5$

$f(5)=-2(5)+5$

Multiplying the terms, we get,

$f(5)=-10+5$

Adding the terms, we get,

$f(5)=-5$

Thus, the value of $f(5)$ is $f(5)=-5$
