Answer:
6 x 4
8 x 3
The product: 24
Hope This Helps! •v•
Step-by-step explanation:
Answer:-3
Step-by-step explanation:do the distributive property. So let's simplify it more: -8g+6=30. Minus the positive 6 to make it a zero then minus the 30 to make it a 24. -8g=24 is what's left. Divide both sides by negative 8: g= -3
Answer:
You got your negatives messed up. The answer was -5y-4x
Step-by-step explanation:
Expression: -8y + 5x + 3y -9x
Your objective: Simplify the expression
The First step, Combine like terms meaning -8y+3y and -9x+5x
Solve, -8y+3y
That would equal -5y
Next solve -9x + 5x
That would equal -4x
Write your expression in simplest form:
-5y-4x
What you did:
You combined like terms but didn't follow the negative rules
Remember: Positive and Negative = Negative
Negative and Negative = Positive
For example -8y + 3y
You chose to add -8 and 3 which you got -11
What you were supposed to do was to subtract.
A helpful trick: Since they are like terms you could rearrange the questions like this 3y-8y+5x-9x, You can see that you have to do subtraction left to right
3y-8y= -5y
5x-9x= -4x
Solution: -5x-4x
Answer:
437mm²
Step-by-step explanation:
First we need to find the total area of the rectangle. The area of a rectangle can be found by using the formula:
A = L x W
L = 15mm
W = 38mm
So now we plug it into our formula.
A = 15mm x 38mm
A = 570mm²
Now that we have the total area, we now need to solve for the area of the triangle.
The area of a triangle can be found by using the formula:
To find the height of the triangle we take the total height and subtract it to the measurement given in the figure.
h = 15mm - 8mm
h = 7mm
b = 38mm
Now that we have both the base and height we can use the formula for the triangle.
Now that we have the area of both the triangle and the rectangle, we simply subtract the area of the triangle to the area of the rectangle.
Shaded Area = 570mm² - 133mm²
Shaded Area = 437mm²
The area of the shaded area is equal to 437mm².
