If w=45,what is the value of 2(w-7)

76

Step-by-step explanation:

if w=45, you'd get 2(45-7) by replacing the variable (w) with its value (45)

so first you'd distribute 2 to the 45 and the 7

now it'd be:

90-14=76

so the answer would be 76! :)

The answer is 76

Step-by-step explanation:

First you swap in the number like so: 2(45-7)

Then you figure out what's is the parentheses first going with PEMDAS like so : 2(38)

Finally you multiply the number getting your final answer which is :76

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
