Answer:
1. 264
2. degree: 6, term: 3xy^5
3. -60x^3-2x^2+9x
4. 6mn^3-4m
5. 8x^3-4x+2
6. -x^2-6x-13
Step-by-step explanation:
2(x+10)=3x-30
2x+20=3x-30
x=50
Therefore, x=50 is your answer.
Remember that vertical angles, angles opposite from each other, have the same degree. That is why you can set up 2(x+10)=3x-30.
I cant see full picture....
We can already tell if a quotient is negative if the divisor or the dividend is a negative number. (Only 1 negative number and 1 positive number, because if there are two negative numbers then the outcome will be a positive.)
Question 4 has one negative number in it so it's already visible that the quotient is already negative. And if we did divide it the answer will be -1.
Question 3 has two negative numbers so we know that the outcome is a positive number. If solve the quotient is 0.023931813 which is clearly not a negative number.
Question 2 has one negative number so the answer will be negative. The quotient will be -23.80952381, which is clearly a negative number.
Question 1 doesn't have any negative numbers so the outcome will also be a positive number. The quotient for question 1 is 0.231578947.
So questions 2 and 4 both have negative quotients. While, questions 1 and 3 have positive quotients.
Answer:
50 in²
Step-by-step explanation:
What is the area in square inches of the trapezoid below.
Area of a trapezoid = 1/2(b1 + b2) h
Where
b1 = First base = 8in
b2 = Second base = 12in
h = Height = 5in
Area of trapezoid = 1/2(8 + 12) × 5
= 1/2 × 20 × 5
= 50 in²
The area of the trapezoid is 50 square inches
