Step-by-step explanation:
Area of a square is side length ^2
To find the length of the side of a square from the area, that’s the square root of the area:
Length of side = sqrt(81) = 9 meters
Area of wall = length of side x height:
Area of wall = 9 x 5 = 45 square meters
Answer: 45 square meters
Let x = the number of green apples, let 4x = the number of red apples
4x + x = 50 Set up the quation
5x = 50 Combine like terms
---- ---- Divide by 5 on both sides to get x alone
5 5
x = 10 green apples
4x = 4(10) = 40 red apples
40 - 10 = 30. Suzanne bought 30 more red apples than green apples.
Complete the statement to describe the expression ab+cd+ef+ghab+cd+ef+gha, b, plus, c, d, plus, e, f, plus, g, h. The expression
solmaris [256]
Answer:
The expression contains FOUR terms and each term contains TWO factors.
Step-by-step explanation:
In algebra, the word term refers to single numbers(10), variables<em>(</em><em>y</em><em>)</em> also the product of the two(<em>10y</em>).
In the given expression : <em>ab+cd+ef+gh .</em>
We have four terms;
A factor is part of a product. For the given equation we Four terms each term will have two factors.
- <em>ab</em>- is a product of factor a and b
- <em>cd- </em>is a product of factor<em> c </em>and<em> d</em>
- <em>ef-</em>is a product of factor<em> e </em>and<em> f</em>
- <em>gh-</em>is a product of factor<em> g </em>and<em> h </em>
Use the identity P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
P(A)=0.50
P(B)=0.60
P(A ∪ B) = 0.30
=>
P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
=(0.50+0.60)-0.30
=0.80
