Answer:
2(x+3)²+12=4
2x+6²+12=4
2x+36+12=4
2x=4-36-12
2x=-44
2x/2x=-44/2x

I need help on this problem.
Answer:
x^2+7x +49/4 and (x+7/2)^2
x^2+bx +b²/4 and (x+b/2)^2
Step-by-step explanation:
Given the expression
x^2+7x+c
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = 7/2
Taking the square of the result
Square of the result = (7/2)^2
Hence c = (7/2)^2
The expression becomes;
x^2 + 7x + (7/2)^2
= x^2+7x +49/4
= (x+7/2)^2
For x^2+bx+d
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = b/2
Taking the square of the result
Square of the result = (b/2)^2
Hence d = (b/2)^2
The expression becomes;
x^2 + bx + (b/2)^2
= x^2+bx +b²/4
= (x+b/2)^2
Round to the nearest hundredth (2 decimal places) when necessary

Jen has 13 fewer marbles than Marty. She has 20 marbles. Which equation can be
solved to find how many marbles Marty has?
F
13 m - 20
H
13m - 20
G
m 13 - 20
3
m - 2013
20-13=7
so i think the answer would be m 13-20?
NO LINKS!!! Find the measurement indicated. Round your answer to the nearest tenth.
Answer:
Solutions given;
Using cosine rule
b²=a²+c²-2*a*c*cos B°
b²=15²+8²-2*15*8*cos39
b²=102.48
b=[tex] \sqrt{102.48} [/tex]
b=10.12
b=10.1
Using sine rule
[tex] \frac{sin A}{BC} = \frac{sin B}{AC} =\frac{sin C}{AB} [/tex]
[tex] \frac{sin 29°}{15} =\frac{sin C}{8} [/tex]
Doing criss cross multiplication
Sin C=[tex] \frac{sin 29°}{15} ×8[/tex]
m<C=Sin -¹(0.29)
m<C=14.98
m<C=15°is a required answer.

If you were to solve the following system using substitution, your new equation would be...
Answer:
2x+ (x-1) = 8
Simplified
3x-1 =8
Step-by-step explanation:
y=x−1
2x+y=8
Take the first equation and everywhere you see y in the second equation substitute x-1
2x+ (x-1) = 8
You can simplify
2x+x-1 =8
3x-1 =8
If you want to solve
3x-1+1 =8+1
3x= 9
Divide by 3
3x/3 =9/3
x=1
Then solve for y
y = x-1
y = 3-1
y=2
