What's the verbal expression for "4(2x-7)"

1 answer:

7 0

Well it's easier to say the expanded version 8x-14
14 less than 8 times a number

But you could say the bracketed version in a strange way
7 less than 2 times a number all times 4

Find the value of cos J rounded to the nearest hundredth

$\bold{ \red{\star{\blue{GIVEN }}}}$

HYPOTHESES= 13

PERPENDICULAR= 12

BASE = ?

$\bold{\blue{\star{\red{TO \: \: FIND}}}}$

$\cos(j) = ?$

$\bold{ \green{ \star{ \orange{FORMULA \: USED}}}}$

PYTHAGORAS THEROM
$\cos(j) = \frac{ BASE}{HYPOTENUSE}$

$\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}$

${h}^{2} = {p}^{2} + {b}^{2}$

${13}^{2} = {12}^{2} + {x}^{2} \\ 169 - 144 = {x}^{2} \\ 25 = {x}^{2} \\ \sqrt{25} = x \\ 5 = x = base$

$\cos(j) = \frac{ BASE}{HYPOTENUSE}$

$\cos(j) = \frac{5}{13} \\ \cos(j) = 0.34$

Is 26 a perfect square? explain.

Aloiza [94]

No because if you were to square it you would get 5.099 and a perfect square is when it is the same number times each other to get a number for example: the square root of 9 is 3 so 3 times 3 is 9.

Hope that helps!
