3. Factor the following trinomial. x^2 - 15x + 56.

makkiz [27]

Answer:

(x-7) (x-8)

Step-by-step explanation:

Break the expression into groups:

= x(x-7) -8(x-7)

Factor out x from:

x^2-7x x(x-7)

Factor out -8 from -8x+56:

-8(x-7)

=x\left(x-7\right)-8\left(x-7\right)

(2) The triangle has an area of 7 & 7/8 cm2 and a base of 5 & 1/4 cm. What is the

Andrew [12]

Answer:

h = 3 cm

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the height )

Here A = 7 $\frac{7}{8}$ = $\frac{63}{8}$ ← expressed as an improper fraction

and b = 5 $\frac{1}{4}$ = $\frac{21}{4}$ , thus

$\frac{1}{2}$ × $\frac{21}{4}$ × h = $\frac{63}{8}$ , that is

$\frac{21}{8}$ h = $\frac{63}{8}$

Multiply both sides by 8 to clear the fractions

21h = 63 ( divide both sides by 21 )

h = 3

If Mr. Kim need to 5/8 yard of wire for a project he has a stick that is 1/8 yard long how many 1/8 in your lungs links does he

jonny [76]

Answer:

5 stick lengths

Step-by-step explanation:

The question is not structured well. However, the following can be deduced

$Wire = \frac{5}{8}yd$

$Stick = \frac{1}{8}yd$

Required

How many of the stick length can be gotten from the wire length

To do this, we simply divide the length of the wire by the length of the stick.

So, we have:

$Number = \frac{Wire}{Stick}$

$Number = \frac{5/8yd}{1/8yd}$

$Number = \frac{5/8}{1/8}$

Using a calculator, we have:

$Number = 5$
