Answer:
x=1
Step-by-step explanation:
First you would do the parentheses.
So, 4 x X= 4x
4x2=8
4x+8=2x+10
subtract 2x on both sides
2x+8=10
subtract 8 from both sides
2x=2
x=1
Answer:
x=3
Step-by-step explanation:
x^2-9
bcos g(-1)=-1
f(g)=x^2+9(-1)=0
x^2-9=0
x^2=9
x=√9
x=3
Answer:
width=x
length=5x
area= 300ft2
area=lxb
300=5x(x)
300=5x^2
x^2=60
x=7.74
7.74(5)=38.7
dimensions are 38.7ft by 7.74 ft

The expressions that are equivalent when m = 1 and m = 4 is;
Option B: 3m + 4 and m + 4 + 2m
We are given m = 1 and m =4;
A) 5m - 3 and 2m + 5 + m
B) 3m + 4 and m + 4 + 2m
C) 2m + 7 and 3m - 3 + m
D) 5m + 3 and 4m + 2 + 2m
For option B; 3m + 4 and m + 4 + 2m
Let's put m = 1
3(1) + 4 = 7
Also, 1 + 4 + 2(1) = 7
Similarly, let us put 4 for m to get;
3(4) + 4 = 16
Also, 4 + 4 + 2(4) = 16
In both cases, the expressions are equivalent and as such option B is the right one.
