Answer:
To find the result of 300 - 650, we can:
a) do 650 + 300 and keep the result sign
b) do 650 + 300 and invert the result sign
c) do 650 - 300 and keep the result sign
d ) perform 650 - 300 and invert the result sign
Step-by-step explanation:
The correct answer is the letter D .
(perform 650 - 300 and invert the result sign)
300 - 650
300 is more than - 650 on the number line this is because of the negative sign of 650
so we can also write it as 650 - 300 and after getting the require result with put the negative sign to the result, so the result will be -350
Keep the sign of the number with the highest absolute value and subtract from it the lowest absolute value.
- (650 - 300)
Subtract the numbers.
- 350
therefore, the answer is d ) perform 650 - 300 and invert the result sign
The first two are alike because you have to add 3 to each side for everything to come out even.
Answer:
84ft^2
Step-by-step explanation:
Given data
Base= 12feet
Height= 14feet
The expression for the area of a triangle is
Area= 1/2bh
Area= 1/2*12*14
Area= 6*14
Area= 84 ft^2
Hence the area of the triangular garden is 84ft^2
