Answer:
X=5
Step-by-step explanation:
4x²=100
x2=100÷4
x²=25
√x²=√25
x=5
Answer:
Step-by-step explanation:
Width =w
Length = 2w + 3
Perimeter = 2*(length +width)
= 2*(2w +3 + w )
= 2*(3w + 3)
= 6w + 6
b) Perimeter = 30 units
6w + 6 = 30
Subtract 6 form both sides
6w = 30- 6
6w = 24
Divide both sides by 6
6w/6 = 24/6
w = 4
l = 2w + 3
= 2*4 + 3
= 8 + 3
= 11
Length = 11 units
Width = 4 units
Answer: 30y2+x and 30y2+x12
Step-by-step explanation:
A polynomial is an algebraic expression consisting of more than one term.
In thise sense, the algebraic expressions are composed of several elements: Terms, Coefficients, Signs, Variables and Exponents. In this case we will focus on the first.
The terms are composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).
For example, in the following expression:
2x-3x
We have two terms separated by the negative sign (-):
2x is the first term
-3x is the second term
Now, according to this explanation, the only two options that have more than one term to be called a polynomial (<em>poly</em> means <u>many</u> and <em>nomial</em> means <u>terms</u>) are the first two:
30y2+x and 30y2+x12
$25.12
Work:
23.99+3.60=27.59
27.59-4.51=23.08
23.08+0.95=24.03
24.03+2.17=26.20
26.20-1.08=25.12
Answer:
See below.
Step-by-step explanation:
A spinner has 12 equal-sized sectors labeled 1 to 12.
The sample space is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12.
The sample space is all the possible outcomes of an event.
