3(x^2-1) + 4(x^2 - 3) = 13
solve for x
Answer:
x=2, x=-2
Step-by-step explanation:
3x²-3+4x²-12=13
7x²=13+12+3
7x²=28
x²=4
x=-2
x=2

2(x+3) = 7
1/2(x + 3) = 7
6(x + 4) = 7
1/6(x + 4) = 27
6(x + 4) = 27
Answer:
1 is correct
2 is incorrect
3 is incorrect
4 is incorrect
5 is correct
Step-by-step explanation:
1. 2(0.5+3) = 1+6 = 7
2. 1/2(0.5+3) = 1/4+3/2 = 7/4
3. 6(0.5+4) = 27
4. 1/6(0.5+4) = 0.75

Step-by-step explanation:
A die has 6 faces with numbers 1, 2, 3, 4, 5, 6.
The faces that are less than 3 are 1, 2.
2 faces have numbers less than 2.
The desired outcome can happen 2 ways, 1 or 2.
The total number of possible outcomes is 6: 1, 2, 3, 4, 5, or 6.
p(event) = (number of desired outcomes)/(total number of possible outcomes)
p(less than 3) = 2/6 = 1/3
The probability of rolling a number less than 3 is 1/3.
Now we find 1/3 of 420.
1/3 * 420 = 420/3 = 140

Find the distance ab give your answer correct to 1. Decimal place
Answer:
AB=10
AB=7.2
Step-by-step explanation:
AB= √{(9-1)²+(8-2)²} = √{8²+6²}=√{64+36}=√100 =10
AB= √{(6-2)²+(2-8)²} = √{4²+(-6)²}=√{16+36}=√52 =7.2
The distance between points A(1, 2) and B(9,8) is 10 and the distance between points A(2, 6) and B(8, 2) is 7.2.
What is a coordinate plane ?A coordinate plane is a plane in which a set of two number lines are represented, horizontal line is called x-axis and vertical line is called y-axis.
In the first coordinate plane,
The coordinate of point A is (1, 2) and coordinate of point B is (9,8),
To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]
Thd distance between A(1, 2) and B(9,8),
AB= [tex]\sqrt{{(9-1)^2+(8-2)^2}}[/tex] = [tex]\sqrt{{8^2+6^2}}[/tex]=[tex]\sqrt{{64+36}}[/tex]=[tex]\sqrt{100}[/tex] =10
In the second coordinate plane,
The coordinate of point A is (2, 6) and coordinate of point B is (8, 2),
To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]
The distance between A(2, 6) and B(8, 2),
AB= [tex]\sqrt{{(8-2)^2+(2-6)^2} }[/tex]= [tex]\sqrt{6^2+(-4)^2}}[/tex]=[tex]\sqrt{{36+16}}[/tex]=[tex]\sqrt{52}[/tex] =7.2

A menu has three meat choices,
three vegetable choices and two desserts
How many ways can you choose your dinner?
Answer:
18 ways
Step-by-step explanation:
Number of Meat choices = 3
Number of Vegetable choices = 3
Number of Desserts = 2
Number of ways dinner can be chosen :
Number of meat choices * Number of vegetable choices * number of desserts
3 * 3 * 2
= 18
Hence, dinner can be chosen in 18 different choices.

formulas A=bh/2 A=bh and I have 6in 4in 6in 10in and I have to find the area
Answer:
Lots of "ifs" here.
A=bh/2 is the formula for the area of a triangle.
A=bh is the formula for the area of a rectangle or a parallelogram.
If the 6 & 4 area the base & height of a rectangle, then (6)(4) = 24 in^2
If the 6 & 10 are the base and height of a triangle, then 1/2(6)(10) = 30 in^2
