☆Find Area of Triangle

Formula: Area of Triangle=

1,2(Base ×Height)

1,2(10×10)

100 ÷ 2 = 50 unit^2

☆Find Area of Circle

Assume: Radius of circle is 5

☆ Área of Circle= Pi × r^2

Pi × 5^2 = Pi × 25

Área of Circle = 78.5 (approximately)

Using Formula

Area of Triangle - Area of Circle

An expression that is equivalent to (-8a-1)-(-7a+5)
horrorfan [7]

Answer:

Step-by-step explanation:

(-8a - 1)- (-7a + 5) = -8a - 1 - 7a*(-1) + 5*(-1) { (-1) is disturbed to all the terms in (-7a +5)}

                         = -8a - 1 + 7a - 5

                         = -8a + 7a -1 - 5 {Combine like terms}

                         = -a - 6

Simplify<br><br> a+a+a=<br> 4b-b<br> 3x2+x2
Reika [66]
<h2>Good morning,</h2>

<em><u>__________________</u></em>

<em><u>Answer</u></em>:

a+a+a = 3a.

4b-b = 3b.

3x²+x² = 4x².

<u><em>explanation</em></u>

a+a+a = 3a.

4b-b = b(4 - 1) = b × 3 = 3b.

3x²+x² = x²(3 + 1) = x² × 4 = 4x².
