Answer:
Option (b) is correct.
Step-by-step explanation:
Given expression "four times the square of a number is thirty-six"
We have to write it mathematically and choose the correct options out of given options.
Consider the given expression "four times the square of a number is thirty-six"
Then
let the number be x ,
Then four times the square of a number written mathematically as 
And given "four times the square of a number is thirty-six" written mathematically as
Therefore, "four times the square of a number is thirty-six" written mathematically as
Option (b) is correct.
Answer:
x-intercepts are (-3,0) and (-4,0).
y-intercept is (0,12).
Step-by-step explanation:
x-intercept is a point where the value of y is zero.
y-intercept is a point where the value of x is zero.
Given equation is :
y=x²+7x+12
put x=0 in given equation to find y-intercept.
y=(0)²+7(0)+12
y= 0+0+12
y= 12
hence, y-intercept is (0,12).
put y=0 in given equation to find x-intercept.
0=x²+7x+12
split the middle term of above equation to make the equation into two groups such that the sum of two numbers should be 7 and their product be 12.
x²+3x+4x+12=0
making two groups and taking common out:
x(x+3)+4(x+3)=0
take (x+3) common,
(x+3)(x+4)=0
x+3=0 or x+4=0
x=-3 or x=-4
hence, x-intercepts are (-3,0) and (-4,0).
First: 5/20
second: 6/19
5/20 x 6/19 = 30/380 = 15/190 = 3/38. The answer is B
Answer: a,e
Step-by-step explanation:
i’m not sure
Answer: 5,14 and -2
Step-by-step explanation:
The coefficient is the number next to the variable.
So this case the coefficients are 5,14 and -2
