Answer:

g(4) = 157

Step-by-step explanation:

g(x) = 8x^2 + 9x - 7

Let x =4

g(4) = 8 * 4^2 +9*4 -7

=8*16 +36 - 7

=128+36-7

=157

Answer:

157

Step-by-step explanation:

g(x)=

${8x}^{2} + 9x - 7$

g(4) =

$8( {4})^{2} + 9(4) - 7 \\g(4) = 8 \times 16 + 36 - 7 \\ g(4) = 128 + 29 \\ g(4) = 157$

Answer:

$g(x) - h(x) = { - x}^{4} - 11x$

Step-by-step explanation:

$g(x) = {6x}^{2} - 4x + {3x}^{4}$

$h(x) = {6x}^{2} + 4 {x}^{4} + 7x$

$g(x) - h(x)$

$({6x}^{2} - 4x + {3x}^{4}) - ( {6x}^{2} + 4 {x}^{4} + 7x)$

${6x}^{2} - 4x + {3x}^{4} - {6x}^{2} - 4 {x}^{4} - 7x$

$( {3x}^{4} - {4x}^{4}) + ( {6x}^{2} - 6x {}^{2} ) + ( - 4x - 7x)$

${ - x}^{4} - 11x$

Please help me with this problem.

Answer:

$x^{\frac{8}{3}}y^{-\frac{5}{6}$

Step-by-step explanation:

Remember the rule for converting radicals and exponents into fractions. The power is the numerator of the fraction, and the nth root is the denominator of the fraction. Also, remember that dividing by an exponent means the exponent will be negative.

$\frac{\sqrt[3]{x^{8} } }{\sqrt[6]{y^{5} } } \\\\\frac{x^{\frac{8}{3} } }{y^{\frac{5}{6} } } \\\\x^{\frac{8}{3}}y^{-\frac{5}{6}$

PLEASE SOMEONE HELP ASAP AND SHOW THE WORK

The sum of two sides of a triangle must be greater than the third side
1) 5+9>14
14>14 It is incorrect so you can’t have these lengths

2)7+7>15
14>15 X

3)1+2>4
3>4 X

4)3+6>8
9>8

6+8>3
14>3

8+3>6
11>6

So the fourth choice is correct
