salantis [7]3 years ago
7 0

Answer:

43

Step-by-step explanation:

Given

2(p - q) + 5(p + q) ← substitute p = 7 and q = - 2 into the expression

= 2(7 - (- 2)) + 5(7 + (- 2))

= 2(7 + 2) + 5(7 - 2)

= 2(9) + 5(5)

= 18 + 25

= 43

Find the area of the composite shape below.
arlik [135]

Answer: 1106.13 (2 decimal places)

Step-by-step explanation:

To work out the area of this composite shape you would have to put the two semi circles together to form a circle and work out the area of the circle (they have provided the radius which is 11in), then work out the area of the rectangle separately.

The formula for the area of a circle is πr^2 (pi x radius squared).

So when you put the numbers in the formula the area is πx11^2=380.1327111

Then to work out the area of the rectangle you would do base x height.

The height of the rectangle is the same as the diameter of the circle (the diameter is double the radius of a circle) which is 22in.

To find the area of the rectangle you do 22x33=726

So then to find the area of the whole shape you would have to add the area of the circle and the rectangle together.

726+380.1327111=1106.13 (2 decimal places).

In what situation can you use only multiplication to find equivalent fractions to a given fraction given example?
olya-2409 [2.1K]
To find equivalent fractions, multiply the numerator<span> AND denominator by the same nonzero whole number. This procedure is used to solve example 4. You can multiply the </span>numerator<span> and the denominator of a fraction by any nonzero whole number, as long as you multiply both by the same whole number! Hope this helped! :)</span>
