[tex](x + 5)(x + 2)[/tex]
Use the algebraic identity,
[tex](x + a)(x + b) \\ = {x}^{2} + (a + b)x + ab[/tex]
Now,
a = 5
b = 2
Substitute the values of a & b in the identity & solve the equation.
[tex] {x}^{2} +( a + b)x + ab \\ = x {}^{2} + (5 + 2)x + 5 \times 2 \\ = {x}^{2} + 7x + 10[/tex]
[tex]✎ \: (x + 5)(x + 2) = {x}^{2} + 7x + 10[/tex]

Theresa had her hair cut to a length of 10 inches. If her hair grows at a rate of 0.02 inch per day, which equation represents the length (L) of Theresa’s hair, in inches, after d days?
d=0.2+10Ld is equal to 0 point 2 plus 10 liters
d=10+0.2Ld is equal to 10 plus 0 point 2 liters
L=0.2+10dcap l is equal to 0 point 2 plus 10 d
L=10+0.2dcap l is equal to 10 plus 0 point 2 d
Answer:
L = 0.02d + 10
Step-by-step explanation:
The hair starts at 10 inches long.
L = 10
Now we add 0.02 inches in length per day.
In 1 day, it grows 0.02 inches.
In 2 days, it grows 0.02 * 2 inches.
In d days, it grows 0.02d inches.
Now we add the starting length, 10, and the growth per day, 0.02d, to get:
L = 0.02d + 10

Solve for a side in right triangles
I don’t know how to do this so please someone teach me how to do this?? I need help here!
Answer:
2.33
Step-by-step explanation:
imagine a circle. its center is A, and it goes through B, so its radius is AB.
then it is important to know that the sum of all the angles in a triangle is 180 degrees.
one angle (at C) is 90. the angle at B is 25. so, the angle at A is 180 - 90 - 25 = 65 degrees.
more back to our circle.
in this circle the line CB is the sine of the angle at A multiplied by the radius.
and AC is the cosine of the angle at A multiplied by the radius.
we can ignore the orientation + and - of these functions, as we are only interested in the absolute length (and we can mirror the triangle, and all the angles and side lengths still stay the same).
=> CB = sin(A)×AB
AC = cos(A)×AB
=> 5 = sin(65)×AB
=> AB = 5 / sin(65)
=> AC = cos(65)×5/sin(65) = 5 × (cos(65)/sin(65)) =
= 5 × cot(65) = 2.33
The value of one of Kevin's baseball cards was $6.00 when he first got it. The value of this card is now $15.00. What is the percent increase in the value of the
card?
Answer:
21
Step-by-step explanation:
So you have to do 6.00 plus 15.00 which is 21.00 so the answer would be 21.00
6.00 + 15.00 = 21.00
what is 1/3 of 1/2 THANKS!
Answer:
1/6
Step-by-step explanation:
Visualizing having one whole pizza.
Mark it into two sections. Each sections the same amount of pizza.
1/3 of 1/2 means take one of the sections called 1/2 of the pizza and mark it into three equal sections.
The other section called 1/2 can also be marked into three equal sections.
That will produce 6 smaller sections of the whole pizza.
Look at the one of the half of the pizza.
One of the three slices of 1/2 of the pizza is 1/3 of 1/2 of the pizza.
Look at the whole pizza. Isn’t the 1/3 of 1/2 = 1/6 of the whole pizza.
1/3(1/2) = 1/6
Answer: 1/6

John and George together raked g of the yard. John 7. raked of that amount. What part of the yard did John rake?
Answer:
7/32
Step-by-step explanation:
John and George together raked 7/8 of the yard. John raked 3/4 of that amount. What part of the yard did john rake?
Proportion of the yard Jake raked = 7/8 x 3/4 = 21/32
Portion of the yard Jake raked = 21/32 - 7/8 = 7/32

this is 90 60 30 formula for example
90 meet 2x
30 meet x
and
60 meet x√3
so 90 meet 5
30 meet 5/2=2.5
and 60 meet 2.5√3
so the answer is 2.5
Answer:
2.5
Step-by-step explanation:
[tex]\sin 30\degree = \frac{x}{5}\\\therefore x = 5\sin 30\degree\\\therefore x = 5 \times \frac{1}{2}\\\therefore x = 2.5[/tex]

Tom can do a job in 210 minutes; Tom and Jerry can do the job together in 52 minutes. How long for Jerry to do the job by himself?
Answer:
158
Step-by-step explanation:
you only need to do is subtract
Jerry can do the job in approx 17 minutes working alone.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Tom can do a job in 210 minutes and assuming Jerry to do the job
in x minutes and work to be 1.
∴ 1/210 + 1/x = 1/52.
1/x = 1/52 - 1/210.
1/x = (210 - 52)/2730.
1/x = 158/2730.
1/x = 79/1365.
x = 1375/79.
x = 17 minutes approx.
