Jared has a wooden board that is 11 ft long. He wants to cut it into 2 pieces so that the longer piece is 4 ft less than 4 times
Kaylis [27]
X+y=11

x is longer than y
x>y
x is 4 less than 4 times y
x=-4+4y

sub back
x+y=11
-4+4y+y=11
-4+5y=11
add 4 to both sides
5y=15
divide both sides by 5
y=3

sub back
x=-4+4y
x=-4+4(3)
x=-4+12
x=8

the pieces are 8ft and 3ft

How do you do this and what's the answer? Pls explain.
Oxana [17]

You don't really need to do any calculations for this as the picture gives it away, but let's just understand the important concept behind this. Basically, tangent is opposite divided adjacent. So for this question:

tan(70) = \frac{x}{8}


When you solve for x, you are left with:

x = 8tan70


Then you need to add the 5 because his eyes cover up the bottom part of the tree, and therefore, your answer is D.

Factorise by grouping: x² - 5x + 2x - 10
Natalka [10]

Answer:

\boxed {\boxed {\sf (x+2)(x-5)}}

Step-by-step explanation:

To factor by grouping, first divide the polynomial into 2 groups with parentheses.

x^2-5x+2x-10

(x^2-5x)+ (2x-10)

Factor the greatest common factor (GCF) out of both binomials.

For the first binomial, the GCF is x.

x(x-5) +(2x-10)

For the second binomial, the GCF is 2.

x(x-5)+2(x-5)

Factor out the common binomial which is (x-5).

(x+2)(x-5)

The factorized form of x²-5x+2x-10 is (x+2)(x-5)
