Answer:
B. 7 cm
Step-by-step explanation:
Answer:
4y^(2)+14y+31
Step-by-step explanation:
First you need to do (y+7)(y+7)
y^2+7y+7y+49
y^2+14y+49
Add it all together
y^2+14y+49+3y^2-15
4y^(2)+14y+31
The area of the parrallelogam is 5*9=45m. The area of the triangle is 1/2*8*9=36m. Added them together, 36+45=81m^2
As we look at the question Answer is :12x +15
The first one = 12 and the second one = 18.
the reason why they have different answers is because of PEMDAS.
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
For the first equation we gave to multiply the exponent (2) to the number (3) because that’s the order of PEMDAS. So, 3x2=6 then + 6=12.
For the second equation there are parentheses, which means we solve the equation inside the parentheses first because of PEMDAS. So, 6+3=9 then x 2 =18.
They have different answers because they are ordered in different ways . PEMDAS controls the order we solve equations in.
Hope this helped:)))
