Answer:
3(x + 2)(2x - 5)
Step-by-step explanation:
Given
6x² - 3x - 30 ← factor out 3 from each term
= 3(2x² - x - 10) ← factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 10 = - 20 and sum = - 1
The factors are + 4 and - 5
Use these factors to split the x- term
2x² + 4x - 5x - 10 ( factor the first/second and third/fourth terms )
= 2x(x + 2) - 5(x + 2) ← factor out (x + 2) from each term
= (x + 2)(2x - 5), thus
2x² - x - 10 = (x + 2)(2x - 5) and
6x² - 3x - 30
= 3(x + 2)(2x - 5) ← in factored form
Answer:
91 Adults
Step-by-step explanation:
Because there are 26 children, you divide it by 2 to get 13. Multiply 13 by 7 for your answer, 91
4 is the answer, divide both sides by 3 and get 4
Answer:
(8y+8)²+(4x²+16)=0
Step-by-step explanation:
Given:
(64y²)+(4x²)+128y+16x+64=0
Find:
Equation into the appropriate form
Computation:
(64y²)+(4x²)+128y+16x+64=0
(8y)²+(2x)²+128y+16x+64=0
(8y)²+(2x)²+2(8y)(8)+2(2x)(4) + 8²=0
(8y+8)²+(4x²+16)=0
Answer:
the Answer is 150x + 12100 ≤ 26500
Step-by-step explanation:
The max weight is 26500 so the weight would have to be the same or less than 26500 (≤)
There is already 12100 killograms on the sipping containter so that is why you have + 12100
and you have 150x because x is the number of 150-kilogram crates
and for as many crates you have to multiply by the weight.
