Answer:
B. 65°
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
180 - 130 = 50
Angles in a triangle add up to 180 degrees.
y + y + 50 = 180
2y + 50 = 180
2y = 180 -50
2y = 130
y = 130/2
y = 65
A fraction actually represents a division problem that can return a decimal real number with which you can solve some problems. ie:4/3 = 4÷3 = 1.333
a. 6×1.25=x 6×1.333=x 6×1.5=x 6×1.75=x 6×2=x make sense?
b. 6×.666=x
c. by definition a cube has equal length sides in all 3 dimensions.
Answer:
<h2><u><em>
2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u></h2>
Step-by-step explanation:
Write an expression for the perimeter of a rectangle with a length of
(3x² + x + 2) and a width of (-x² – 5x + 1).
P = 2 × (L + W)
<u><em>2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u>
if you want the result:
4x²−8x+6
Answer:
1: B. 2: 6n^6+9n^5+4n^2-4n. 3: D. 4: 6b^2-15b-9. 5: 48x^2-4x-4
Step-by-step explanation:
1.
A trinomial is a polynomial with three terms. The expression 7v^2 +2v +2 has 3 terms.
2.
A polynomial in standard form has its powers listed from highest power to lowest power. The terms are 6n^6, 4n^2, 9n^5, and -4n. Remove the bottom numbers to find 6, 2, 5, and 1. Next, put them in order. 6, 5, 3, 1. Then, re-add the bottom numbers. 6n^6+9n^5+4n^2-4n.
3. A sixth degree polynomial is one with a sixth degree power. So, the answer is either C or D. Next, let's look at the terms. The expression here has 4 terms. So, the answer is D.
4 and 5:
To solve expressions in this form, (a+b)(c+d), turn the expression into an equivalent one, ac+ad+bc+bd. Plug in the numbers (with a negative mark if its -a or a-b) into that expression to get your answer.
4 simplifies out into 6b^2+3b-18b-9, which can be simplified into 6b^2-15b-9
5 simplifies out into 48x^2+12x-16x-4, which can be simplified into 48x^2-4x-4.
The area of a square given its diagonal (d) is computed as follows:
In this case, the diagonal is 10 units long, then the area is:
