Answer:
B isosceles with sides sqrt (61)
Step-by-step explanation:
Find the two sides' lengths via pythagorean theorem to be
sqrt ( 5^2 + 6^2) = sqrt (61)
Given,
The expression is (2x+2)(x+3).
Required
The product of the expressions.
The product of the expression is,
Hence, the product of the expression is 2x^2+8x+6.
A chemical bond<span> is a lasting attraction between </span>atoms<span> that enables the formation of </span>chemical compounds<span>. The bond may result from the </span>electrostatic force<span> of attraction between atoms with opposite charges, or through the sharing of electrons as in the </span>covalent bonds<span>. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or </span>ionic bonds<span> and "weak bonds" such as </span>Dipole-dipole interaction<span>, the </span>London dispersion force<span> and </span>hydrogen bonding<span>.</span>
Answer:
She didn't put the sign's in the proper place, it should be ( x + 3 ) ( x - 7 )
Step-by-step explanation:
( x - 3 ) ( x + 7 ) = x² + 7x - 3x - 21 = x² + 4x - 21
( x + 3 ) ( x - 7 ) = x² - 7x + 3x - 21 = x² - 4x - 21
