(x - 4)(2x + 3)
Using foil:
2x^2 + 3x - 8x - 12
Simplify.
2x^2 - 5x - 12 is the product after using FOIL.
Answer:
Angle k = 14°,L = 70° and N = 96°
Step-by-step explanation:
According to the question,Enzo drew Triangle K L N. In Enzo’s triangle, Measure of angle K is represented as x degrees. The measure of Angle L is 5 times Measure of angle K. The measure of Angle N is 16 degrees less than 8 times Measure of angle K.
From here,we know that angles in a triangle sum up to 180°
If angle k = x
Angle L = 5x
And angle N = 8x - 16
Sum of a all three is equal to 180°
(8x - 16) + x + 5x = 180
14x -16 = 180
X = 196/14
X= 14.
Therefore,angles k = 14°, L = 70° and N= 96°
Let's now assume that the question was to find the angles k,l and n which is already written above and to pick the correct statement relating to the question.
My statement here is( since we weren't given the complete question) that the triangle is a scalene triangle
Answer:
Their welders earn $50,000 annually.
Step-by-step explanation:
Given : 
n = 100
To Find : The ship building association wishes to find out whether their welders earn more or less than $50,000 annually.
Solution :
n = 100
Since n > 30
So we will use z test
Substitute the values
Refer the z table for p value
p value = 0.9599
α= 0.05
Since p value > α
So we accept the null hypothesis .
Hence their welders earn $50,000 annually.
Object A. You can use the area theorem to solve. Just do base x height to get the area of a shape.
