Answer:
The expression that could be used is (-4)(3) + (-4)() ⇒ B
Step-by-step explanation:
Let us revise the distributive property:
<em>The product of a number and the sum of 2 other numbers equal to the sum of the products of the number with the other 2 numbers</em>
- a(b + c) = ab + ac
We will use this rule to solve the question
∵ The product of -4 and 3 = -4 × 3
→ We can right 3 as (3 +
)
∵ 3 = (3 +
)
∴ -4 × 3 = -4(3 +
)
→ By using the rule above
∵ -4(3 + ) = (-4)(3) + (-4)(
)
∴ -4 × 3 = (-4)(3) + (-4)(
)
∴ The expression that could be used is (-4)(3) + (-4)()
The area of the garden is 74 square feet
<h3>How to determine the area of the garden?</h3>The complete question is added as an attachment
From the attached figure, we have the following shapes and dimensions:
- Rectangle: 10 by 5 feet
- Trapezoid: Bases = 10 and 6; Height = 3
The rectangular area is
A1 = 10 * 5
Evaluate
A1 = 50
The area of the trapezoid is
A2 = 0.5 * Sum of parallel bases * height
This gives
A2 = 0.5 * (10 + 6) * 3
Evaluate
A2 = 24
The total area is
Total = A1 + A2
This gives
Total = 50 + 24
Evaluate
Total = 74
Hence, the area of the garden is 74 square feet

By using scientific notation we calculated (2.310⁵)(1.5
10⁴) we got 345
10⁷.
Given that,
(2.310⁵)(1.5
10⁴)
By using scientific notation
The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.
Now, we calculate
(2.310⁵)=2.5
100000=230000
(1.5 10⁴)=1.5
10000=15000
Now,
=23000015000
=3450000000
=345 10⁷
Therefore, By using scientific notation we calculated (2.310⁵)(1.5
10⁴) we got 345
10⁷.
