What is the expression in factored form? please show steps on how to get both answers!
1. x2+13x +42
2. 9x^2−4
^ means its number beside is the exponent.
Answers
Answer:
1. The factored form of the given expression is (x+7)(x+6).
2. What is the expression in factored form . 9x^2 -4
Step-by-step explanation:
1. The given expression is,
The degree of the expression is 2, the constant term is 42, and the coefficient of x is 13.
Use factoring by grouping method
To find the factor form, we have to find two numbers whose sum is 13 and whose product is 42.
The factors of 42 are,
From which the sum of 6 and 7 is 13.
So We can write the 13x as 7x+6x.
2. This expression can be factorized using the difference of squares which can be illustrated as follows:
A^2 - B^2 = (A+B)(A-B)
In the given example:
sqrt(9x^2) = 3x
sqrt(4) = 2
and the two squares are separated by a negative sign
Therefore, the difference of squares is applicable
Based on this, factoring the given expression would give us:
9x^2 - 4 = (3x+2)(3x-2)

The fraction that is equivalent to 4/7 among the given set of fractions is 8/14
Equivalent of fractionsFrom the question, we are to determine the fraction that is equivalent to 4/7
To determine this, we will reduce each of the given fractions to their lowest terms where possible
For 6/9Dividing both the numerator and denominator by 3, we get
2/3
∴ 6/9 is not equivalent to 4/7
For 8/14Dividing both the numerator and the denominator by 2, we get
4/7
∴ 8/14 is equivalent to 4/7
For 2/3This is the lowest form of this fraction and it is not equivalent to 4/7
For 8/21This is the lowest form of this fraction and it is not equivalent to 4/7
Hence, the fraction that is equivalent to 4/7 among the given set of fractions is 8/14.

What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0. A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively
Given;
h(x) = 4x – 1...(1)
h(x) = -9
Substituting the value of h(x) in equation 1
-9=4x-1
-9+1=4x
-8=4x
x=-8/4
x=-2
Therefore, the solution for the equation will be x=-2

Robert bought 3 baseball caps for the same amount and 1 baseball jersey that cost $45. Without tax, the total cost of the items is $90. What is the cost of each baseball cap?
Answers
Answer: The cost of each baseball cap = $15.
Step-by-step explanation:
Let x = cost of each baseball cap
Given; cost of each baseball jersey= $45
Total coast of 3 baseball caps and 1 baseball jersey = $90
i.e. [tex]3x+45=90[/tex]
[tex]\Rightarrow\ 3x=45\\\\\Rightarrow\ x=\dfrac{45}{3}\\\\\Rightarrow\ x= 15[/tex]
Hence, the cost of each baseball cap = $15.

The right triangle has a big square with an area of 73 sq. units . What could the area of the small squares be .
Answers
9514 1404 393
Answer:
E. 40 and 33
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the areas of the smaller squares will match the area of the largest square.
The answer choices have sums of ...
A: 76; B: 73; C: 96; D: 66; E: 73
So, choices with the correct sum are B and E.
If this question asks you to "choose all that apply," then B & E will be your answer choices.
__
We note that the areas of the smaller squares appear to be not much different in size. If their areas were 23 and 50, the smaller square would be less than half the size of the larger one. So, if the figure is drawn approximately to scale, the choice of 40 and 33 is a better choice.

Kiaya has to have at least $100 in her checking account to avoid a fee from the bank. She has $376 in her account now. Each week, she makes a $25 withdrawal. For how many weeks can she make this withdrawal and avoid a fee?
Answers
Answer:
$500 a week
Step-by-step explanation:
Hope I can help.
Kiaya can make a $25 withdrawal for 11 weeks without incurring a fee.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
Kiaya needs to have at least $100 in her checking account to avoid a fee from the bank. She has $376 in her account now, so she can make $376 - $100 = $276 worth of withdrawals before she will be charged a fee.
Each week, she makes a $25 withdrawal.
To determine the number of weeks she can make this withdrawal before being charged a fee, we divide the total amount she can withdraw ($276) by the amount she withdraws each week ($25).
So, Kiaya can make $276 / $25 = 11 withdrawals before she will be charged a fee.
Therefore, she can make a $25 withdrawal for 11 weeks without incurring a fee.
