To solve these you have to follow the orders of operation(BEDMAS), which means brackets, exponents, division, multiplication, addition, subtraction all in that order.
A) This is false. 7x6+4=46 and does not equal 7x10 or 70.
B) This is false as well. The answer haste be 19 and 16-(4+7) does not equal 19. You add up what is in the brackets first and then subtract.
This means that C and D have to be true.
C) 10+(6/3)=12
10+2=12 True
D) 2+5x7=37
2+35=37
Also true
Answer:
9π/4 - 4.5 unit^2.
Step-by-step explanation:
The are of the segment = area of the sector - area of the triangle.
Area of the sector = 1/4 * area of the circle
= 1/4 π 3^2
= 9π/4. unit^2
Area of the triangle
= 1/2 * 3 * 3
= 9/2 unit^2.
So the answer is 9π/4 - 4.5 unit^2.
D because of the distributive property
A. The answer is 4y+3 you distribute and get 4y^2 +4y+1-4y^2+2 then combine like terms which is (4y^2-4y^2)+(4y)+ (1+2) and equals 4y+3
B. The answer is 14w^3 +2w^2 bc you distribute again which gives you 20w-10w^2-6w^3+12w^2 and then combine like terms (20w^3-6w^3)+(-10w^2+12w^2) and equals to 14w^3+2w^2
C. The answer is 3y^2-5y+2 bc you distribute again which is 7y^2-3y-4y^2-2y+2 and then combine like terms (7y^2-4y^2)+(-3y-2y) +2 and gives you 3y^2-5y+2
Answer:
$513
Step-by-step explanation:
Find 9ft multiplied by 6ft, it is 54
Do $228 ÷ 54, which is equal to 4.2 repeated
Multiply 4.2 repeated by (13.5 × 9), = 513
