Answer:

<u>x² + 7x + 10 = (x + 2) (x + 5)</u>

Step-by-step explanation:

Given: x squared plus 7 x plus 10

The algebraic expression is ⇒ x² + 7x + 10

To factor the expression, we need to find two numbers, their product = 10

and their sum = 7

Factor the number 10

10 = 1 * 10  ⇒ 1 + 10 = 11

10 = 2 * 5  ⇒ 2 + 5 = 7

So, the numbers are 2 and 5

<u>So, x² + 7x + 10 = (x + 2) (x + 5)</u>

A rectangle has a perimeter of 26 cm and one of its sides has length of 5 cm
otez555 [7]

Answer:5 by 8 by 5 by 8

Step-by-step explanation: the perimeter is 26 and one side if 5 so you know that another side is also 5. So add 5 and 5 together you get 10. Then subtract 10 from the perimeter(witch we know is 26) and you end up with 16. we know that the last two side lengths are the same so divide 16 by two and the sidle length is 8.

Help on this 3 questions pleaseeeee!!!!
ra1l [238]

Answer:

14. D

15. A

16. A

Step-by-step explanation:

14. Point slope form formula: y-y₁=m(x-x₁).

When graphing you always want to think x/y for your slope.

X-axis increases by 2 and the Y-axis increases by 10, which would make the slope (m) 2/10 = 1/5.

If your slope is does not come out correct, then you can prove your point.

15. The given information is (-2,2): m=-1.

Given the Point slope formula: y-y₁=m(x-x₁), you can replace m to -1, y₁=2 and x=+2. (Two negatives would make a positive.)

Your answer: y-2=-(x+2)

16. Given: y=4x-7; (3,0)

Parallels lines: Same slope different y-intercepts.

A and D has the same slope and different y-interecepts, but your answer would be A because the equation that was given as a negative y-intercepts.

FIND THE UNIT RATE AND ROUND TO THE NEAREST HUNDREDTHS IF NECESSARY. Jasigreen's class opened last year and serviced 6,840 custo
Vladimir [108]
<span>6840 customers ... 45 days<span>
x customers = ? ... 1 day

If you would like to know how many customers were in Jasigreen's class in 1 day, you can calculate this using the following steps:

6840 * 1 = 45 * x
6840 = 45 * x     /45
x = 6840 / 45
x = 152 customers

<span>The correct result would be </span>152 customers<span>.</span></span></span>
