Answer:
12
Step-by-step explanation:
Answer: -8x^2-14x
Step-by-step explanation:
A square is a rectangle, so this shape would be classified as a rectangle.
The area of a rectangle is length times width, so that means the area is 2x(-4x-7), which equals -8x^2-14x. Therefore, the area is -8x^2-14x.
Answer:
Step-by-step explanation:
First we need to calculate the sum of interior angle of the pentagon. The sum of interior angle of any polygon is expressed as S = (n-2)180
Given n = 5
S = (5-2)180
S = 3*180
S = 540°
Hence the measure of interior angle of the pentagon is 540°. The sum of all the interior angles will give us;
<A+<B+<C+<D+<E = 540
Given m∠A = m∠D = x°, m∠B = m∠C = (4x)° and the measure of reflex angle at E is (8x)°. If the reflex angle at E is (8x)°, the interior angle at E will be (360-8x)°
Substituting the given values into the formula to get x;
x+4x+4x+x+360-8x = 540
10x-8x = 540-360
2x = 180
x = 180/2
x = 90°
To find the measure of the reflex angle at vertex E, we will substitute x = 90 into the vertex E = (8x)°.
vertex E = 8(90)
vertex E = 720°
She will have to buy less than 7 fish.
40 divided by 5 = 8
8-1=7
