Answer:

Step-by-step explanation:

When subtracting a negative, the two negatives cancel out. The rule is that two like signs become positive.

Therefore, +(+) =+ and -(-) = +

So, the equation would be 21 + 5.

Use the distributive property with factoring to find the equivalent expression. 24n + 32w = (3n + w)

pashok25 [27]

Answer:

Step-by-step explanation:

24n + 32w = (3n + w)

We're asked to use distributive property, this means that we have to find a way that the given expression on the left hand side is equal to the given incomplete exresssion on the right hand side. In so doing, we're fulfilling the distributive property tag.

Given 3n, 3 factorises 24 into 8, and at the same time, factorises 32 into 4. Thus, we can then conclude that

24n + 32w = 8(3n + 4w)

Can someone actually help me with this please and thank you

Musya8 [376]

Answer:

a. F(x)=10x-1 , the value of F(-2) is

F(-2)=10(-2)-1

f(-2)= -20-1

f(-2)= -21

b. g(x)= -5x+13 , the value of g(1)

g(1)= -5(1)+13

g(1)= -5+13

g(1)= 8 or +8

c. h(x)= $x^{2}$ -x-12 , the value of h(3) is

h(3)= $3^{2}$ -3-12

h(3)=9-3-12

h(3)= -6
